First, assign your column id:

{name: 'Roll Number', id: 'rollNum', field: 'roll', width: 'auto', defaultValue: ""},

If you are trying to hide or show the column the solution is:

// to hide column with id="rollNum"
grid.styleColumn("rollNum", "display: none;");

// to show it
grid.styleColumn("rollNum", "display: table-cell;");

Its very simple. Just add "hidden: true" to the column structure.

structure: [ {name: 'Roll Number', field: 'roll', width: 'auto', defaultValue: "", hidden: true}, {name: 'Name', field: 'name', width: '100px', defaultValue: ""}, {name: 'Class', field: 'class', width: '75px', defaultValue: ""} ],
