How to make some columns align left and some column align center in React Table - React

Question

Hello Stack overflow members

This is array for the column headers. I want column 1 to column 5 left align (all the header, sub header and table data cells of column 1 to column 5 to be left aligned) while I I want column 6 to column 8 to be centre aligned (all the header, sub header and table data cells of column 1 to column 5 to be centre aligned). Please help me to solve this as I can only make either all columns center or all columns left aligned.

I want to implement this particular style on column 6 to 8 header as shown in this image. .

If you can help me, please provide a demo on CodeSandbox

This is my Header Data

const columns = [
 {
    Header: 'Column 1',
        columns: [
           {
               Header: 'S Column 1',
               accessor: 'firstName'
           }
      ]
  },
  {
      Header: 'Column 2',
       columns: [
         {
            Header: 'S Column 2',
            accessor: 'firstName'
          }
       ]
     },
    {
            Header: 'Column 3',
            columns: [
    {
            Header: 'S Column 3',
            accessor: 'firstName'
          }
         ]
   },
    {
          Header: 'Column 4',
          columns: [
    {
            Header: 'S column 4',
            accessor: 'firstName'
     }
    ]
      },
     {
     Header: 'Column 5',
    columns: [
    {
    Header: 'S column 5',
     accessor: 'firstName'
    }
   ]
   },
  {
     Header: 'Column 6',
     columns: [
  {
        Header: 'S column 6a',
        accessor: 'firstName'
  },
   {
        Header: 'S column 6b',
        accessor: 'firstName'
    },
    {
        Header: 'S column 6c',
        accessor: 'firstName'
     },
    {
         Header: 'S column 6d',
         accessor: 'firstName'
    }
  ]
     },
      {
     Header: 'Column 7',
     columns: [
     {
      Header: 'S column 7',
         accessor: 'firstName'
   }
    ]
     },
      {
        Header: 'Column 8',
        columns: [
      {
       Header: 'S Column 8a',
       accessor: 'firstName'
      },
     {
       Header: 'S Column 8b',
       accessor: 'firstName'
     },
    {
    Header: 'S Column 8c',
    accessor: 'firstName'
    },
    {
      Header: 'S Column 8d',
      accessor: 'firstName'
      }
     ]
      },
      ];

Method 1:

Something like this should do the job

columns: [
           {                 
              accessor: "firstName",
              Header: () => (
                    <div
                      style={{
                        textAlign:"right"
                      }}
                    >S Column 1</div>)
           },

Play here

Update after OP comment

but for columns which will be centre aligned , their sub cell data will also be centre aligned

Manipulate cell styles like this

Cell: row => <div style={{ textAlign: "center" }}>{row.value}</div>

Play it here

Method 2:

Use can use the headerClassName and specify a class name, in that class you can specify the rule text-align:center

So the code will look like

const columns = [{
  Header: 'Column 5',
  accessor: 'name',
  headerClassName: 'your-class-name'
},
{
......
}
]

Method 3:

If you have lot of headers, adding headerClassName in all headers is a pain. In that case you can set the class name in ReactTableDefaults

import ReactTable, {ReactTableDefaults} from 'react-table';

const columnDefaults = {...ReactTableDefaults.column, headerClassName: 'text-left-classname'}

and in the ReactTable, use like this

<ReactTable
 ...
 ...
 column = { columnDefaults }
 />

Note: if you are using bootstrap you can assign the inbuilt class text-center to headerClassName
