Changing column width in react-table

Question

I have a react-table and I am trying to change the column size. I've tried editing the "width" value within the columns, editing the values in the scss stylesheet, and adding inline styling, but nothing is working. Where do I make css changes to this react-table ? Any help would be appreciated. Any example I see changes it within the column area as I've tried.

import React, {useState, Fragment} from "react";
import {useTable, useFilters, useGlobalFilter, useRowSelect} from "react-table";
import dataSet from "../data";
import {IndeterminateCheckbox} from './TableCheckbox';


function DeployTable() {

    function DefaultColumnFilter({
                                     column: { filterValue, preFilteredRows, setFilter },
                                 }) {
        const count = preFilteredRows.length

        return (
            <input
                value={filterValue || ''}
                onChange={e => {
                    setFilter(e.target.value || undefined) // Set undefined to remove the filter entirely
                }}
                placeholder={`Search ${count} records...`}
            />
        )
    }

    const [data] = useState(dataSet);

    const [columns] = useState([

        {
            width:'20',
            Header: "Deploy Id",
            accessor: "deploy_id"

Answer 1

You need to use a layout hook (useBlockLayout, useAbsoluteLayout or useFlexLayout) so the specified width is applied. Important: all those hooks set a default column width to 150px.

You can see an example in Full Width Resizable Table.

---

If you don't want to use a layout hook, you can use getHeaderProps and getCellProps according to your needs, acessing minWidth and width values:

function Table({ data }) {
  const columns = useMemo(
    () => [
      {
        Header: 'Name',
        accessor: 'name',
        maxWidth: 400,
        minWidth: 140,
        width: 200,
      },
      {
        Header: 'Qty',
        accessor: 'quantity',
        maxWidth: 70,
        minWidth: 50,
        width: 60,
      },
    ],
    [],
  );

  const {
    getTableBodyProps,
    getTableProps,
    headerGroups,
    rows,
    prepareRow,
  } = useTable({ columns, data, getRowId });

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              <th
                {...column.getHeaderProps({
                  style: { minWidth: column.minWidth, width: column.width },
                })}
              >
                <span>{column.render('Header')}</span>
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody {...getTableBodyProps()}>
        {rows.map(row => {
          prepareRow(row);
          return (
            <tr {...row.getRowProps()}>
              {row.cells.map(cell => {
                return (
                  <td {...cell.getCellProps({
                      style: {
                        minWidth: cell.column.minWidth,
                        width: cell.column.width,
                      },
                    })>
                    {cell.render('Cell')}
                  </td>
                );
              })}
            </tr>
          );
        })}
      </tbody>
    </table>
  );
}

Try this: You can style rows, cells, columns in the same way (it's known as prop getter pattern)

In your code: search for ...column.getHeaderProps()

Pass an object with style to column.getHeaderProps() & you can also add more props if required along with style:

...column.getHeaderProps({
                          style: {width: '200px'}
                         })

or

<th {...column.getHeaderProps()}
style= {{ ...column.getHeaderProps.style, ...getColumnStyle(column) }} >

In above code, getColumnStyle(column) is my custom function where I return style for that particular column.

Explanation: It is a headless UI library. means, It only provides logic and no UI (build your own UI), We can style table however we want, It is called prop getter pattern. You can read more on here: https://kentcdodds.com/blog/how-to-give-rendering-control-to-users-with-prop-getters
