Material-React-Table MRT , Select option in the columns on update mode have probleme , I need help

[SAKONE278]

for exemple : {
accessorKey: 'state',
header: 'State',
muiTableBodyCellEditTextFieldProps: {
select: true, //change to select for a dropdown
children: states.map((state) => (

{state}

)),

    header: 'Region',
   
    enableColumnOrdering: false,

    enableEditing: true, //disable editing on this column

    enableSorting: false, 
    size: 80,

    muiTableBodyCellEditTextFieldProps: {
      select: true,

      children:  
      regions.map((reg) => (
              <MenuItem key={reg._id} value={reg.name}>
            
                {reg.name}
              </MenuItem>
            ))
    },

  },
