Running Grid API Commands

To run a grid API command use the grid's run_api() method. The method accepts two arguments. The first is a string representing the command and the second is the page the grid is on.

The example below uses the grid API to select and deselect rows.

grid_options = """

    rowSelection: 'multiple',

        cellStyle: {textAlign: 'center'},
        headerClass: 'font-bold'
    }, 
      columnDefs: [
      {headerName: "Make", field: "make"},
