When I render a button inside a material-ui table, the button is not clickable

My table looks as such:
<TableContainer component={Paper} style={{height: "40vh", width: "90vh"}}>
<Table size="small" sx={{ minWidth: 200 }}>
<TableHead>
<TableRow>
<TableCell align="center" width="90"></TableCell>
{consequences_description.map((description) => (
<TableCell align="center" width="90">{description}</TableCell>
)
)}
</TableRow>
</TableHead>
<TableBody>
{risk_matrix.map((row, row_index) => (
<TableRow
key={row_index}
sx={{ '&:last-child td, &:last-child th': { border: 0 } }}
>
<TableCell component="th" scope="row">
{likelyhood_description[row_index]}
</TableCell>
{row.map( (column, column_index) => (
<TableCell align="center">
<ToggleButton
risk={column}
row_index={row_index}
column_index={column_index}
/>
</TableCell>
))}
</TableRow>
))}
</TableBody>
</Table>
</TableContainer>
The button inside the table is called <ToggleButton/> and it looks as such:
<ThemeProvider theme={filtersTheme}>
<Button variant="contained" color={handleColor()} onClick={console.log("Clicked")} >{risk}</Button>
</ThemeProvider>
As soon as the table renders, the console shows "Clicked", meaning the onClick function gets called for the button as soon as it renders inside the table for some reason, but I am not able to click it and fire the onClick function. Is there a way to do this?

Try to call the onClick function like this:
onClick={() => { console.log('Clicked');

ReactJS table with material ui

I am trying to use the material UI minimized table to create a dashboard https://material-ui.com/pt/components/tables/
I ran into an issue that I'm stuck with for the last 5 hours. I could successfully render the data from my database to display in the table. However, when I retrieve the data using the map function, all is displayed in one single row x5.
Picture: Front-end view
I'm trying to display the name and data in different rows and not "Sue Flavio John Doe rajid" because each is a different object.
I'd appreciate some help to understand where is my logical mistake.
function EmployeeList() {
const [employeeList, setEmployeeList] = useState([]);
console.log(employeeList);
useEffect(() => {
Axios.get("http://localhost:4000/vacations_cs_read").then((response) => {
setEmployeeList(response.data);
});
}, []);
const Row = () => {
const [open, setOpen] = React.useState(false);
const classes = useRowStyles();
return (
<React.Fragment>
<TableRow className={classes.root}>
<TableCell>
<IconButton
aria-label="expand row"
size="small"
onClick={() => setOpen(!open)}
>
{open ? <KeyboardArrowUpIcon /> : <KeyboardArrowDownIcon />}
</IconButton>
</TableCell>
<TableCell component="th" scope="row">
{employeeList.map((val, key) => {
return <td>{val.employeeName}</td>;
})}
</TableCell>
<TableCell align="left">
{employeeList.map((val, key) => {
const day = new Date(val.employeeStartDay).toLocaleDateString(
"pt-BR"
);
return <td>{day}</td>;
})}
</TableCell>
<TableCell align="left">
<p>-</p>
</TableCell>
<TableCell align="left">
<p>-</p>
</TableCell>
<TableCell align="left">
<p>-</p>
</TableCell>
</TableRow>
<TableRow>
<TableCell style={{ paddingBottom: 0, paddingTop: 0 }} colSpan={6}>
<Collapse in={open} timeout="auto" unmountOnExit>
<Box margin={1}>
<Typography variant="h6" gutterBottom component="div">
History
</Typography>
<Table size="small" aria-label="purchases">
<TableHead>
<TableRow>
<TableCell>From</TableCell>
<TableCell>To</TableCell>
<TableCell align="left">Days</TableCell>
<TableCell align="left">Paid</TableCell>
</TableRow>
</TableHead>
<TableBody>
{/* {row.history.map(() => (
<TableRow>
<TableCell component="th" scope="row"></TableCell>
<TableCell></TableCell>
<TableCell align="left"></TableCell>
<TableCell align="left"></TableCell>
</TableRow>
))} */}
</TableBody>
</Table>
</Box>
</Collapse>
</TableCell>
</TableRow>
</React.Fragment>
);
};
Row.propTypes = {
row: PropTypes.shape({
name: PropTypes.string,
startDate: PropTypes.string,
shift: PropTypes.string,
daysReceived: PropTypes.number,
daysUsed: PropTypes.number,
daysLeft: PropTypes.number,
history: PropTypes.arrayOf(
PropTypes.shape({
amount: PropTypes.number,
customerId: PropTypes.string,
date: PropTypes.string,
})
),
}),
};
return (
<div>
<TableContainer component={Paper}>
<Table aria-label="collapsible table">
<TableHead>
<TableRow>
<TableCell />
<TableCell>Name</TableCell>
<TableCell align="left">Employment Date</TableCell>
<TableCell align="left">Days received</TableCell>
<TableCell align="left">Days used</TableCell>
<TableCell align="left">Days left</TableCell>
</TableRow>
</TableHead>
<TableBody>
{employeeList.map((val, key) => (
<Row />
))}
</TableBody>
</Table>
</TableContainer>
</div>
);
}

Well, you are not giving the data to each row in the map call where you iterate over the employees. And then, instead you iterate of the whole thing again in each cell..
This should work:
const Row = ({val}) => {
const [open, setOpen] = React.useState(false);
const classes = useRowStyles();
return (
<React.Fragment>
<TableRow className={classes.root}>
<TableCell>
<IconButton
aria-label="expand row"
size="small"
onClick={() => setOpen(!open)}
>
{open ? <KeyboardArrowUpIcon /> : <KeyboardArrowDownIcon />}
</IconButton>
</TableCell>
<TableCell component="th" scope="row">
{val.employeeName}
</TableCell>
<TableCell align="left">
{(new Date(val.employeeStartDay)).toLocaleDateString("pt-BR")}
</TableCell>
<TableCell align="left">
<p>-</p>
</TableCell>
<TableCell align="left">
<p>-</p>
</TableCell>
<TableCell align="left">
<p>-</p>
</TableCell>
</TableRow>
<TableRow>
<TableCell style={{ paddingBottom: 0, paddingTop: 0 }} colSpan={6}>
<Collapse in={open} timeout="auto" unmountOnExit>
<Box margin={1}>
<Typography variant="h6" gutterBottom component="div">
History
</Typography>
<Table size="small" aria-label="purchases">
<TableHead>
<TableRow>
<TableCell>From</TableCell>
<TableCell>To</TableCell>
<TableCell align="left">Days</TableCell>
<TableCell align="left">Paid</TableCell>
</TableRow>
</TableHead>
<TableBody>
{/* {row.history.map(() => (
<TableRow>
<TableCell component="th" scope="row"></TableCell>
<TableCell></TableCell>
<TableCell align="left"></TableCell>
<TableCell align="left"></TableCell>
</TableRow>
))} */}
</TableBody>
</Table>
</Box>
</Collapse>
</TableCell>
</TableRow>
</React.Fragment>
);
};
Row.propTypes = {
row: PropTypes.shape({
name: PropTypes.string,
startDate: PropTypes.string,
shift: PropTypes.string,
daysReceived: PropTypes.number,
daysUsed: PropTypes.number,
daysLeft: PropTypes.number,
history: PropTypes.arrayOf(
PropTypes.shape({
amount: PropTypes.number,
customerId: PropTypes.string,
date: PropTypes.string,
})
),
}),
};
return (
<div>
<TableContainer component={Paper}>
<Table aria-label="collapsible table">
<TableHead>
<TableRow>
<TableCell />
<TableCell>Name</TableCell>
<TableCell align="left">Employment Date</TableCell>
<TableCell align="left">Days received</TableCell>
<TableCell align="left">Days used</TableCell>
<TableCell align="left">Days left</TableCell>
</TableRow>
</TableHead>
<TableBody>
{employeeList.map((val, key) => <Row val={val} key={key}/>)}
</TableBody>
</Table>
</TableContainer>
</div>
);

The structure you should be using should look something like this:
function Row(props) {
// you can access the employee object as `props.employee`
...
}
...
{employeeList.map((val, key) => <Row key={key} employee={val} />}
Each time you call the row function, it gives you a new row. For it to know what data should be in that row, you should be passing that data as a prop, instead of using the state. The flow of data would therefore be that the render method has a list of employees, and it calls the row builder function once with each of them, which gives back a list of rows to render.

Can not render Table correctly in React

I'm trying to make a table with Material UI in React like that:
Here is my code:
return (
<>
<div className="main-wrapper">
<TableContainer component={Paper}>
<Table style={{ minWidth: '650px' }} aria-label="caption table">
<caption>Test</caption>
<TableHead>
<TableRow>
<TableCell align="left" colSpan={1}>
Something else
</TableCell>
<TableRow align="center">
{daysMaps.map(day => (
<TableCell align="center" colSpan={90}>
{day}
</TableCell>
))}
</TableRow>
<TableRow align="center">
{daysMaps.map(() => {
{shifts.map(shift => {
<TableCell align="center">
{shift}
</TableCell>
})}
})}
</TableRow>
</TableRow>
</TableHead>
</Table>
</TableContainer>
</div>
</>
);
I just write the Table Head codes here.
These are the problems:
The shifts(morning, noon, night) doesn't appear on the page
A warning is shown on the console: Warning: validateDOMNesting(...): <tr> cannot appear as a child of <tr>.
How can I fix this problem and make a correct table?

You somehow mixed up the code and forgot the return statements:
<TableRow align="center">
{daysMaps.map(() => {
return shifts.map(shift => {
return <TableCell align="center">{shift}</TableCell>;
});
})}
</TableRow>
Alternatively, exchange the curly braces with round ones, then you can omit the return statement. I made a small codepen for you.
The warning seems to be related to the way material-ui renders the table.

I suspect you can't put TableRow inside a TableRow tag.
You'll need to use rowpspan somewhere. This is a guess, but perhaps like this:
return (
<>
<div className="main-wrapper">
<TableContainer component={Paper}>
<Table style={{ minWidth: '650px' }} aria-label="caption table">
<caption>Test</caption>
<TableHead>
<TableRow>
<TableCell align="left" colSpan={1} rowSpan="2">
Something else
</TableCell>
{daysMaps.map( (day, i) => (
<TableCell key={i} align="center" colSpan={3}>
{day}
</TableCell>
))}
</TableRow>
<TableRow>
{daysMaps.map(() => {
{shifts.map( (shift,i) => (
<TableCell key={i} align="center">
{shift}
</TableCell>
))}
})}
</TableRow>
</TableHead>
</Table>
</TableContainer>
</div>
</>
);
I've added key attributes in for you. You'll get an error without those,

this error means you cannot put a <tr> tag as a child of <tr> nor <td> as a child of <td>
change your code to this
<TableHead>
<TableRow>
<TableCell align="left" colSpan={1}>
Something else
</TableCell>
<TableCell align="center">
{daysMaps.map(day => (
<span style={{textAlign:"center"}}>
{day}
</span>
))}
</TableCell>
<TableCell align="center">
{daysMaps.map(() => { {shifts.map(shift => {
<span style={{textAlign:"center"}}>
{shift}
</span>
})} })}
</TableCell>
</TableRow>
</TableHead>

display an full-width row in material-ui table react

I want to display some data in a table this is my JSX code:
const StudentsTable = (props) => {
const classes = useStyles();
return (
<TableContainer component={Paper}>
<Table className={classes.table} aria-label="simple table">
<TableHead>
<TableRow>
<TableCell>NR.</TableCell>
<TableCell align="right">NUME</TableCell>
<TableCell align="right">E-MAIL</TableCell>
<TableCell align="right">NR.TELEFON</TableCell>
<TableCell align="right">CLASA</TableCell>
<TableCell align="right">ACTIUNI</TableCell>
</TableRow>
</TableHead>
<TableBody>
{props.students.length > 0 ? (
props.students.map((student, i) => (
<TableRow key={student.studentName}>
<TableCell component="th" scope="row">
{i + 1}
</TableCell>
<TableCell align="right">{student.studentName}</TableCell>
<TableCell align="right">{student.studentEmail}</TableCell>
<TableCell align="right">{student.studentPhone}</TableCell>
<TableCell align="right">{student.clasa}</TableCell>
<TableCell align="center" className={classes.actionsCell}>
<BootstrapButton variant="primary" size="sm">
EDITARE
</BootstrapButton>
<BootstrapButton
variant="danger"
size="sm"
onClick={() => props.deleteStudent(student.studentName)}
>
STERGERE
</BootstrapButton>
</TableCell>
</TableRow>
))
) : (
<Typography variant="h5">
NU EXISTA ELEVI ADAUGATI.{"\n"} PUTETI ADAUGA APASAND PE BUTONUL
"ADAUGA ELEVI"
</Typography>
)}
</TableBody>
</Table>
</TableContainer>
);
};
when the props.students it's an empty array I want to return a single full-width row with this message: NU EXISTA ELEVI ADAUGATI.{"\n"} PUTETI ADAUGA APASAND PE BUTONUL "ADAUGA ELEVI" but in my app, the table looks something like this:
how to fix it?

In the place where you want to render a full row
use
<TableRow><TableCell colSpan={6}>"your message"</TableCell></TableRow>

Nested Material UI Dialog with Table not rendering

I have a component that renders a fullscreened <Dialog> with a <Table>.
Every row in this <Table> contains a <TableCell>, which contains a <Button> component.
When pressed, another, not fullscreened <Dialog> containing a <Table> should pop up and show what the object in the main <Table> contains.
Something like this:
---Basket---Total---Products----Date-----
-------A---------3------------[1]------someDate-- // [1] being the button
onClick() of [1] triggers the smaller <Dialog>
---Name---Price---Quantity---
----Prod-------3----------1------- // Nested <Dialog>
Now, I have a method that just parses the date I get from the backend into the Date column in the main <Table>.
Funnily, if I press the <Button> for the second, smaller <Dialog>, the method gets called again, everything freezes for 5 seconds and a bunch of windows pop up over each other.
I have my open variable in the state, so I thought that the whole thing gets rerenderer when I toggle it. Which would make sense.
I tried using <Modal> which would actually be a better option, but it just crashes Chrome. Screen becomes black with parallel lines across.
So, basically, I'm doing two loops in the <Dialog> component.
Here's the code using <Dialog>:
<Dialog
open={this.props.loadBasketsWindowOpen}
transition={Transition}
keepMounted
onClose={this.handleClose}
aria-labelledby="alert-dialog-slide-title"
aria-describedby="alert-dialog-slide-description"
fullScreen
>
<DialogTitle id="alert-dialog-slide-title">
<p style={centerDiv}>{"Baskets: "}{this.props.openBaskets.length}</p>
<hr style={horizontalLineStyle}/>
</DialogTitle>
<DialogContent>
<div style={centerDiv}>
<Table>
<TableHead>
<TableRow>
<TableCell style={tableTextStyle}>User</TableCell>
<TableCell style={tableTextStyle}>Total</TableCell>
<TableCell style=tableTextStyle}>Products</TableCell>
<TableCell style={tableTextStyle}>Date</TableCell>
<TableCell></TableCell>
</TableRow>
</TableHead>
<TableBody>
{this.props.baskets !== undefined ?
this.props.baskets.map(basket => {
return(
<TableRow key={basket.id}>
<TableCell style={tableTextStyle}>
{basket.user}
</TableCell>
<TableCell style={tableTextStyle}>
€{basket.total}
</TableCell>
<TableCell style={tableTextStyle}>
<Button onClick={this.onToggle}>
{basket.posBasketItems.length}
<Dialog
open={this.state.innerTableWindowOpen}
onClose={this.handleClose}
aria-labelledby="alert-dialog-slide-title"
aria-describedby="alert-dialog-slide-
description"
>
<DialogTitle>
<p style={centerDiv}>
{"Cart: "}
{basket.length} Products
</p>
<hr style={horizontalLineStyle}/>
</DialogTitle>
<DialogContent>
<Table>
<TableHead>
<TableRow>
<TableCell>
Name
</TableCell>
<TableCell>
Price
</TableCell>
<TableCell>
Quantity
</TableCell>
</TableRow>
</TableHead>
<TableBody>
{basket.items.map(item => {
return (
<TableRow key={item.id}>
<TableCell>
{item.name}
</TableCell>
<TableCell>
{item.price}
</TableCell>
<TableCell>
{item.quantity}
</TableCell>
</TableRow>
);
})}
</TableBody>
</Table>
</DialogContent>
</Dialog>
</Button>
</TableCell>
<TableCell>
{this.parseDate(basket.date)}
</TableCell>
<TableCell>
<Button
onClick={()=>this.setToCurrentBasket(basket)}
>
<ADD_TO_SHOPPING_CART />
</Button>
</TableCell>
</TableRow>
);
}) : ''}
</TableBody>
</Table>
</div>
</DialogContent>
<DialogActions>
<div>
<MuiThemeProvider theme={cancelButtonTheme}>
<Button
variant="raised"
onClick={this.closeOpenBasketsWindow}
color="secondary"
>
CANCEL
</Button>
</MuiThemeProvider>
</div>
</DialogActions>
</Dialog>
Here's onToggle() and the state
state = {
innerTableWindowOpen: false
};
onToggle = () => {
this.setState({
innerTableWindowOpen: !this.state.innerTableWindowOpen
});
}
I would appreciate any idea to fix this with <Dialog> or <Modal> or even something similar.
The idea is to have a short preview of what's in the basket before choosing one.
Thanks!
