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

Method 1:

Something like this should do the job

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

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

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>

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
