How to increment a cell in AG Grid React tabel?

Pretty new with AG Grid library and stuck on updating the cells.
In reality, I need to do the task with dates, but just to keep it simple, I'll explain my problem with simple numbers.
I have
Start, which is 1.
Stop, which is already defined
End
Duration, which is already defined
My goal
Start = Duration + End
End = Start + Stop
Here is what I have so far
Desired result
Sandbox Link and code below
import React from "react";
import { AgGridReact } from "ag-grid-react";
import "./styles.css";
import "ag-grid-community/dist/styles/ag-grid.css";
import "ag-grid-community/dist/styles/ag-theme-alpine.css";
function App() {
const start = 1;
const [gridApi, setGridApi] = React.useState(null);
const [gridColumnApi, setGridColumnApi] = React.useState(null);
const columnDefs = [
{
headerName: "Name",
field: "name"
//valueGetter: (params) => console.log(params)
},
{
headerName: "start",
field: "start",
valueGetter: (params) => {
if (params.node.rowIndex !== 0) {
return params.getValue("end") + params.data.duration;
} else {
return start;
}
}
},
{ headerName: "stop", field: "stop" },
{
headerName: "end",
colId: "end",
valueGetter: (params) => {
return params.data.start + params.data.stop;
}
},
{
headerName: "duration",
field: "duration",
colId: "duration"
}
];
const rowData = React.useMemo(
() => [
{
name: "John",
stop: 10
},
{
name: "David",
stop: 15
},
{
name: "Dan",
stop: 20
}
],
[]
);
const durationArray = [5, 8, 6];
const rowDataWithStart = React.useMemo(() => {
if (durationArray) {
return (
rowData &&
rowData.map((row, i) => ({
...row,
start: start,
duration: durationArray[i]
}))
);
}
}, [start, rowData, durationArray]);
const defaultColDef = {
flex: 1,
editable: true
};
const onGridReady = (params) => {
setGridApi(params.api);
setGridColumnApi(params.columnApi);
};
return (
<div className="App">
<h1 align="center">React-App</h1>
<div className="ag-theme-alpine">
<AgGridReact
columnDefs={columnDefs}
rowData={rowDataWithStart}
defaultColDef={defaultColDef}
domLayout={"autoHeight"}
onGridReady={onGridReady}
></AgGridReact>
</div>
</div>
);
}
export default App;
Any help will be appreciated

you can use valueGetter for this. I have modified the valueGetter in you code
const columnDefs = [
{
headerName: "Name",
field: "name"
//valueGetter: (params) => console.log(params)
},
{
field: "start",
valueGetter: ({ data }) => {
const end = data.stop + data.start
return data.duration + end;
}
},
{ field: "stop" },
{
field: "end",
valueGetter: ({ data }) => {
return data.start + data.stop
}
},
{
headerName: "duration",
field: "duration"
}
];

Put Link into json using hook (React)

i have a question, i want to add this command line:
Cell: ({ row }) => <a href={row.original.lastName}>{row.original.lastName}</a>
into 'lastName',using hook in reactjs, for example:
Before:
const [columns, setColumns] = useState(
[
{
id:'firstName',
Header: 'First Name',
accessor: 'firstName',
},
{
Header: 'Last Name',
accessor: 'lastName',
},
]
);
setColumns(???)
Result:
[
{
id:'firstName',
Header: 'First Name',
accessor: 'firstName',
},
{
Header: 'Last Name',
accessor: 'lastName',
Cell: ({ row }) => <a href={row.original.lastName}>{row.original.lastName}</a>
},
]
Best regards
Giuseppe

Please find a small working solution as below. Please feel free to replace the button click with your side effect which can be an API call or any action side effect. Just for simplicity, I have used a button.
import React, { useState } from "react";
import ReactDOM from "react-dom";
const Row = ({ row }) => (
<a href={row.original.lastName}>{row.original.lastName}</a>
);
function App() {
const [columns, setColumns] = useState([
{
id: "firstName",
Header: "First Name",
accessor: "firstName"
},
{
Header: "Last Name",
accessor: "lastName"
}
]);
const createRowsForLastName = () => {
const replaceColumnForLastName = columns.map(column => {
if (column.accessor === "lastName") {
return {
...column,
Cell: <Row row={{ original: { lastName: "some name" } }} />
};
}
return { ...column };
});
setColumns(replaceColumnForLastName);
};
console.log(columns);
return (
<div className="App">
<button onClick={createRowsForLastName}>Create Row!</button>
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

How to prevent rows adjustment after they are expanded?

I am working with antd table and antd transfer component and I am facing a small challenge with CSS.
I have created a small example with codesandbox. If I try to expand a row, you will see that other columns try to adjust themselves. Is there a way I could prevent this? I do not want the rows to adjust themselves. The table should feel the same after the expansion as it was before the expansion.
This is code from the sandbox link I shared above that generates the table.
import React from "react";
import ReactDOM from "react-dom";
import "antd/dist/antd.css";
import "./index.css";
import { Transfer, Table, Tag } from "antd";
function difference(listOne, listTwo) {
const set1 = new Set(listOne);
const set2 = new Set(listTwo);
const difference = new Set([...set1].filter(x => !set2.has(x)));
return Array.from(difference);
}
// Customize Table Transfer
const TableTransfer = ({ leftColumns, rightColumns, ...restProps }) => (
<Transfer {...restProps}>
{({
direction,
filteredItems,
onItemSelectAll,
onItemSelect,
selectedKeys: listSelectedKeys,
disabled: listDisabled
}) => {
const columns = direction === "left" ? leftColumns : rightColumns;
const rowSelection = {
getCheckboxProps: item => ({ disabled: listDisabled || item.disabled }),
onSelectAll(selected, selectedRows) {
const treeSelectedKeys = selectedRows
.filter(item => !item.disabled)
.map(({ key }) => key);
const diffKeys = selected
? difference(treeSelectedKeys, listSelectedKeys)
: difference(listSelectedKeys, treeSelectedKeys);
onItemSelectAll(diffKeys, selected);
},
onSelect({ key }, selected) {
onItemSelect(key, selected);
},
selectedRowKeys: listSelectedKeys
};
return (
<Table
rowSelection={rowSelection}
columns={columns}
dataSource={filteredItems}
size="small"
/>
);
}}
</Transfer>
);
const mockTags = ["eg", "gg", "e"];
const mockData = [];
for (let i = 0; i < 20; i++) {
let data = {
key: i.toString(),
title: `eq${i + 1}`,
description: `description of eq${i + 1}`,
disabled: false, //i % 4 === 0,
tag: mockTags[i % 3]
};
if (i % 2 === 0) {
const children = [
{
key: i.toString() + "children",
title: `children-${i + 1}`,
description: `children description-${i + 1}`,
disabled: true,
tag: "tag"
}
];
data["children"] = children;
}
mockData.push(data);
}
const originTargetKeys = mockData
.filter(item => +item.key % 3 > 1)
.map(item => item.key);
const leftTableColumns = [
{
dataIndex: "title",
title: "Name"
},
{
dataIndex: "tag",
title: "Tag",
render: tag => <Tag>{tag}</Tag>
},
{
dataIndex: "description",
title: "Description"
}
];
const rightTableColumns = [
{
dataIndex: "title",
title: "Names"
},
{
dataIndex: "tag",
title: "Tag",
render: tag => <Tag>{tag}</Tag>
},
{
dataIndex: "description",

}
];
class App extends React.Component {
state = {

this.setState({ targetKeys: nextTargetKeys });
};
render() {
const { targetKeys, disabled } = this.state;
return (
<div>
<TableTransfer

itemsUnit: "Equipments",
notFoundContent: "The list is empty",
searchPlaceholder: "Search here"
}}
/>
</div>
);
}
}
ReactDOM.render(<App />, document.getElementById("container"));

You want to constraint your columns width, for example, try this on the leftTableColumns and notice the difference with the right one:
const leftTableColumns = [
{
dataIndex: 'title',
title: 'Name',
width: '45%'
},
{
dataIndex: 'tag',
title: 'Tag',
render: tag => <Tag>{tag}</Tag>,
width: '10%'
},
{
dataIndex: 'description',
title: 'Description',
width: '40%'
}
];
Refer to Table Column API.

React-Table not rendering data

I am trying to render some data in a react-table component however the data doesn't load. I have tested out with dummy data of the exact same format and it works fine. However when I make an API call and get data of the same format and push it to the list of data i'm passing to the react-table the table does not render it. Please help me identify the issue. Cheers
Setting up the columns:
columns: [
{
Header: "Employee ID",
accessor: "EmployeeID"
},
{
Header: "First Name",
accessor: "FirstName"
},
{
Header: "Last Name",
accessor: "LastName"
},
{
Header: "Date of Birth",
accessor: "DateOfBirth",
},
{
Header: "Status",
accessor: "Status",
},
{
Header: "Gender",
accessor: "Gender",
},
{
Header: "UpdatedDateUTC",
accessor: "UpdatedDateUTC",
}
]
What the data looks like:
{"EmployeeID":"63c571b3-bff0-4ce1-94f7-255c235580fa","FirstName":"Clive","LastName":"Thomas","Status":"ACTIVE","DateOfBirth":"/Date(697248000000+0000)/","Gender":"M","UpdatedDateUTC":"/Date(1533706298000+0000)/"}
My API call and how I'm saving the data item to state. (I console logged the value of the data I'm getting and it is in the correct format)
fetch('http://localhost:3100/employees')
.then((resp) => {
return resp.json()
})
.then((data) => {
let temp = this.state.posts;
temp.push(data.Employees[1])
this.setState({posts: temp})
console.log(this.state.posts)
})
.catch((error) => {
console.log(error, "catch the hoop")
})
The state and the 'posts' list storing the posts in state at bottom (with dummy data):
state = {
title: "Choose an Endpoint",
activeOrg: "Orginisation",
isExpanded: false,
activeLink: 0,
authLink:'',
response: '',
post: '',
responseToPost: '',
show: false,
modalContent:"",
token:'',
verifier:'',
org:'',
orginisations: [
{ id: 1, name: "ANU"},
{ id: 2, name: "Bar"},
{ id: 3, name: "FANG"},
{ id: 4, name: "Atlassian"}
],
list: [
{ id: 1, name: "Employees" },
{ id: 2, name: "Leave Applications" },
{ id: 3, name: "Pay Items" },
{ id: 4, name: "Payroll Calendars" },
{ id: 5, name: "Pay Runs" },
{ id: 6, name: "Pay Slips" },
{ id: 7, name: "Settings" },
{ id: 8, name: "Superfund Products" },
{ id: 9, name: "Timesheets" }
],
columns: [
{
Header: "Employee ID",
accessor: "EmployeeID"
},
{
Header: "First Name",
accessor: "FirstName"
},
{
Header: "Last Name",
accessor: "LastName"
},
{
Header: "Date of Birth",
accessor: "DateOfBirth",
},
{
Header: "Status",
accessor: "Status",
},
{
Header: "Gender",
accessor: "Gender",
},
{
Header: "UpdatedDateUTC",
accessor: "UpdatedDateUTC",
}
],
posts: [
{"EmployeeID":"63c571b3-bff0-4ce1-94f7-255c235580fa","FirstName":"Clive","LastName":"Thomas","Status":"ACTIVE","DateOfBirth":"/Date(697248000000+0000)/","Gender":"M","UpdatedDateUTC":"/Date(1533706298000+0000)/"}
]
}
Render function:
render() {
let myClass=""
let EndpointList = (
<div>
{this.state.list.map((i) => {
i.id === this.state.activeLink ? myClass="endpoint activeLink" : myClass="endpoint"
return <Endpoint
key={i.id}
name={i.name}
myClass={myClass}
clicked={(event) => this.handleClickEndpoint(i, i.id)}/>
})}
</div>
);
let orgContainer = ""
this.state.isExpanded ? orgContainer="orgItem expanded" : orgContainer="orgItem notExpanded"
let OrgList = (
<div className={orgContainer}>
{this.state.orginisations.map((o) => {
return <Orginisation
key={o.id}
name={o.name}
clicked={(event) => this.handleClickOrg(o,o.id)}
></Orginisation>
})}
</div>
);
var activeContent=<ReactTable columns={this.state.columns} data={this.state.posts} noDataText={"Loading..."}></ReactTable>
// const columns = Object.keys(this.state.data[0]).map((key, id)=>{
// console.log(key)
// return {
// Header: key,
// accessor: key,
// }
// })
return (
<Router>
<Route path='/' exact render={
() => {
return (
<div className='authenticateContainer'>
<a href={this.state.authLink} className='fill-div'>Click to Auntheticate</a>
</div>
)
}
}/>
<Route path='/home' render={
() => {
return (
<div>
<div className='sideBar'>
<div className='logoHolder'>
<img className='logo' alt='Logo' src={'./Assets/logo.png'}></img>
</div>
{EndpointList}
{OrgList}
<div style={{}} className="org button" onClick={this.expandOrg}>
<img className="orgLogo" alt='Logo' src={'./Assets/orgLogo.png'}></img>
{this.state.activeOrg}
</div>
</div>
<div className="container" id={this.state.title}>
{/* <button onClick={() => { this.setCredentials() }}>CLICK ME</button> */}
<div className="contentContainer">
<div className="head">
{this.state.title}
</div>
{activeContent}
</div>
</div>
</div>
)
}
} />
</Router>
);
}
}
Instantiating the react-table (also in render function above):
var activeContent=<ReactTable columns={this.state.columns} data={this.state.posts} noDataText={"Loading..."}></ReactTable>
I have also printed the dummy data that is successfully being inserted into the list as well as the API data which is not. As you can see they are clearly identical:

Not sure if this will resolve your issue, but IMO you should refactor this to be
fetch('http://localhost:3100/employees')
.then((resp) => {
return resp.json()
})
.then((data) => {
let temp = [...this.state.posts]
temp.push(data.Employees[1])
this.setState({
posts: temp,
data: data
})
console.log(this.state.posts) //this will not have the newest values yet, setState is async
})
.catch((error) => {
console.log(error, "catch the hoop")
})
It's not good practice to perform manipulations on react state

Why are you pushing Employees[1]? That would be the second record.

How to get objects in array of object in React Native

I'm kind of lost to access some info in my static data. Here's the data :
{
"info1": {
"label": "label",
"class": "class-css",
"title": "title",
"text": "text",
"number": "20",
"tags": [
{
"name": "#twitter"
},
{
"name": "#myspace"
}
]
},
"info2": {
"label": "label",
"class": "class-css",
"title": "title",
"text": "text",
"number": "20",
"tags": [
{
"name": "#instagram"
},
{
"name": "#facebook"
}
]
}
}
Then I get the first info like that :
this.setState({
currentLabel: this.state.labels["info1"]
})
This is why I want and then I want to display info in a component and it's working until I try to get tags information. I tried a .map() but without success and error.
<View>
<Text>{infoDetail.title}</Text>
<Text>{infoDetail.text}</Text>
<Text>How do I get "tags" information</Text>
</View>
Is it possible to access these objects in the array "tags" ?

yes you can call tags as follows infoDetail.tags and do map on it
render(){
const tagItems = infoDetail && infoDetail.tags.map((item, index) => {
return <Text key={index}>{item.name}</Text>
});
return(
<View>
<Text>{infoDetail.title}</Text>
<Text>{infoDetail.text}</Text>
{tagItems}
</View>
)
}

Here is a full working code. Since your labels state property is an object, you need to map it somehow. I've chosen Object.values here. You can use Object.keys or even Object.entries according to your needs.
I've used a separate Info component and passed the values to it, then render there. In this component, we are again mapping the tags, then rendering the list.
class App extends React.Component {
state = {
labels: {
info1: {
label: "label1",
class: "class-css",
title: "title",
text: "text",
number: "20",
tags: [
{
name: "#twitter",
},
{
name: "#myspace",
},
],
},
info2: {
label: "label2",
class: "class-css",
title: "title",
text: "text",
number: "20",
tags: [
{
name: "#instagram",
},
{
name: "#facebook",
},
],
},
},
}
render() {
const { labels } = this.state;
return (
<div>
{
Object.values( labels ).map( value =>
<Info label={value} key={value.label} /> )
}
</div>
);
}
}
const Info = ( props ) => {
const { title, text, tags } = props.label;
const tagList = tags.map( tag => <p key={tag.name}>{tag.name}</p> );
return (
<div style={{ border: "1px solid gray", marginTop: "-1px" }}>
<p>{title}</p>
<p>{text}</p>
<div>{tagList}</div>
</div>
);
};
ReactDOM.render(
<App />,
document.getElementById("root")
);
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<div id="root"></div>
Update
If your data is totally static then #Xavi A.'s method is a good option. I don't know how is your list but I provide a simple code including something like you want here.
const labels = {
info1: {
label: "label1",
class: "class-css",
title: "title",
text: "text",
number: "20",
tags: [
{
name: "#twitter"
},
{
name: "#myspace"
}
]
},
info2: {
label: "label2",
class: "class-css",
title: "title",
text: "text",
number: "20",
tags: [
{
name: "#instagram"
},
{
name: "#facebook"
}
]
}
};
class App extends React.Component {
state = {
currentLabel: Object.keys(labels)[0]
};
handleInfoChange = info => this.setState({ currentLabel: info });
renderList = () => (
<ul>
{Object.keys(labels).map(info => (
<Item key={info} info={info} onClick={this.handleInfoChange} />
))}
</ul>
);
render() {
const { currentLabel } = this.state;
return (
<div>
{this.renderList()}
<Info currentLabel={currentLabel} />
</div>
);
}
}
const Item = props => {
const { info, onClick } = props;
const handleClick = () => onClick(info);
return <li onClick={handleClick}>{info}</li>;
};
const Info = props => {
const { currentLabel } = props;
const { title, text, tags } = labels[currentLabel];
const tagList = tags.map(tag => <p key={tag.name}>{tag.name}</p>);
return (
<div style={{ border: "1px solid gray", marginTop: "-1px" }}>
<p>{title}</p>
<p>{text}</p>
<div>{tagList}</div>
</div>
);
};
ReactDOM.render( <App />, document.getElementById( "root" ) );
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<div id="root"></div>

Probably something like this.
<Text>{infoDetail.tags.map(tag => {/*render */})}</Text>

You can try Object.keys() and Array.prototype.reduce() to get your favorite data:
const data = {
"info1": {
"label": "label",
"class": "class-css",
"title": "title",
"text": "text",
"number": "20",
"tags": [
{
"name": "#twitter"
},
{
"name": "#myspace"
}
]
},
"info2": {
"label": "label",
"class": "class-css",
"title": "title",
"text": "text",
"number": "20",
"tags": [
{
"name": "#instagram"
},
{
"name": "#facebook"
}
]
}
};
const tags = Object.keys(data).reduce((result, key) => {
return result.concat(data[key].tags);
}, [])
console.log(tags);
/* tags = [
{
"name": "#twitter"
},
{
"name": "#myspace"
},
{
"name": "#instagram"
},
{
"name": "#facebook"
}
] */

No need to save all the static data in your state, you can keep your state cleaner by just saving the selected label:
onLabelSelect = label => {
//label will be "info1" for example
this.setState({
currentLabel: label
})
}
Then in your render:
render(){
//get infoDetail from staticData
const infoDetail = staticData[this.state.currentLabel]
return (
<View>
<Text>{infoDetail.title}</Text>
<Text>{infoDetail.text}</Text>
{infoDetail.tags.map( ({name}) => <Text>name</Text>)}
</View>
)
}
Note about the map. This:
{infoDetail.tags.map( ({name}) => <Text>name</Text>)}
is a shorter version of:
{infoDetail.tags.map( item => {
return <Text>item.name</Text>
})}
