How to add a textField to a specific row inside a table onclick of a button using reactjs & material ui

I want to add multiple textfield on to a specific row inside a table whenever the specific row add button is clicked, currently I am able to add text field onclick of add button but whenever the add button is clicked the textfield is getting added in every row of the table. Also the add icon needs to be next to the last text field but currently I could only achieve it having it on the 1st text field. Please someone help me out here. Image of what i have achieved so far.
As you can see I'm trying to add textfields on 1st row ,but it is automatically adding textfields in every row of table.

There are a few ways to do it. A quick way is to (as Muhammad said) handle the button click for each row.
Meaning that you need to pass to the addCustomFile method the row Id and store this in your array.
Then when you map the customRow array in your main TableBody make sure to add the two custom columns only if there is a match between the customRow.rowID and the row ID you are currently rendering.
I`ve modified your sandbox https://codesandbox.io/s/infallible-resonance-qn64l?file=/src/App.js:1807-1820

you have to handle button click for each row. right now just one state so therefore it is showing in each cell

Maybe give this a try

hopefully it solves what you are looking for, if not please provide me with a bit more detailed issue of what exactly you want
This at the moment just works for one row and maybe for two rows you can try it by adding a it is not exactly a text field area but it should be a similar fix.

Select HTML Table Row and Identify DB Record ID

I’m developing a simple CRUD based application for upskilling purposes.
Currently, the application outputs the result of a select query to a HTML table using JSTL. The last column of this table has a Delete link for each record which sends the parameters action=delete&id=1 to the server. The id param value part of the href of these links are obviously dynamically generated with JSTL based on the database record key that is passed into the JSP with the database results.
Instead of having this Delete column, I want the user to “select” a row and click a Delete button at the bottom of the table, which will send the above parameters to the server.
I am unsure how to accomplish the following to achieve this:
(1) In Javascript, how can I allow the user to “select” a table row. I don’t want the table to have radio buttons. The behaviour should be that the user clicks the row, the entire row colour changes and JS retains the index of the selected row. Only one row can be selected at a time. If the user clicks the row again, it becomes deselected, i.e. the colour is returned to its original colour and JS no longer identifies that row index as being highlighted.
(2) If I don’t have a Delete link specific to each db record, how can I identify the key of the db record to be deleted and return this to the server when the Delete button is clicked. For example, currently if the record in the db has an PK of 123456, my JSTL will generate a href action=delete&id=123456 for that specific Delete link. So, how can I link that id to the selected table row without having to actually display that id in the HTML table.

1) There are plenty of ways to do it. I suppose all of them will involve the use of something like var rows = document.getElementsByTagName("tr"); or its jquery (or other framework) equivalent. Or some other selector, maybe by CSS classname, could be used. Followed by a loop in which you deselect all the rows that were not clicked and select only the one that was recently clicked. Changing the color equals just changing the css class assigned to the DOM element basically.
2) You will use Javascript either to append to the DOM an html form with hidden inputs (<input type='hidden'.../>) and then submit it via Javascript (if you're Ok with moving to a different page and back). Or you can use Javascript to send an Ajax request to the delete servlet, and then remove the particular tr from the page when you receive a success response back.

Changing the tabular data to another table using jquery

I tried to implement to display data in a table with the button click. Now I am trying to move the data from the table to the below the continue table. In this code, when I enter the input value from the json object and click the submit button, data will display in a table with a continue button and a empty table below.When I click continue the data in the above table should move to table which is located below the continue button. Here is my code [Sample http://jsfiddle.net/e254w/6/] Can anyone please suggest the idea of implement the scenario?

One way to approach this would be to remove the row from the first table and append it to the second.
This line finds the second row in the first table, removes it if it exists and appends it to the second table.
$('#datatable').find('tr').eq(1).remove().appendTo($('#seconddatatable'));

Updated fiddle - this works for me first entering 122233334444, then entering 122223355552

SlickGrid V2.0 Column name/id does not follow column when dragging

I have an application (using SlickGrid) where I need to get the column name or id at any time when user clicks on a cell (this pulls up a menu specific to the data in that column/cell). Grid works fine initially but if the column is moved (drag/drop), the column name/id does not follow the drop but remains mapped to it's initial column position.
Has anyone else seen this and, if so, how did you fix it?
Thanks

Are you trying to reuse the list of columns defined in your html code? You should get the list of columns from the grid instead. The following code should do what you are expecting (i.e. printout the name of the column in which you clicked a cell):
grid.onClick.subscribe(function(e,args) {
var allColumns=grid.getColumns();
console.log(allColumns[args.cell].name);
});
You can add that code in one of the examples provided with the source code (say "example3-editing.html"), drag-drop some columns around and check the console after clicking on a cell.

How to add a row below the currently selected row (based on a dropdown input) using jQuery?

I have a table with a bunch of rows. In the last column of every row, there is a dropdown. When the dropdown changes, I need a new table row to appear below the row where the user selected the dropdown item. However, I also need the new row to have different data depending on what was selected in the dropdown.
Is any of this possible using only jQuery?
Note that I'm using ASP.NET for back-end development, so if a solution can be found without using ID's that would be great.

$("table select").live("click",function(){
var row=$(this).parent().parent();//add some .parent() untill you get the TR element
var val=$(this).val(); //<select> value if you want to use it for some conditions
$("<tr><td>....</td></tr>").insertAfter(row);
})

It's simple enough to add the HTML using JQuery. However, if you intend to save this data back to the server, the default ASP.NET process (using ViewState) will ignore the new rows. Instead, you would need to directly read the submitted form properties.
