  ]}
  options={{
    sorting: true,
    search: false,
    paging: false,
    fixedColumns: {
      left: 2,
    },
  }}
 />

How Can I divide a specific column data into two parts and apply css on that column ? Please help me as I am new in material-table.

I'm not sure this is exactly what you need, but since there is no out-of-the-box way to do this directly inside material-table, you can use a custom render and create a <Grid> element inside your cell:

render: rowData => {
  return (
    <Grid container spacing={0} className={classes.rateRevContainer}>
      <Grid item xs={6} className={classes.rateCol}>
        {rowData["fillRate"]}
      </Grid>
      <Grid item xs={6} className={classes.revCol}>
        {rowData["revenue"]}
      </Grid>
    </Grid>
  );
