I am using the following code for my grid.

var view1 = {
cells: [[
{name: 'Sel', editor: dojox.grid.editors.bool , width: '16px'},
{name: 'str', field: "star", formatter: starFormatter, width: '16px'},
{name: 'read', field: "read", formatter: readFormatter, width: '16px'},
{name: 'Subject',width: "60%", field: "subject", styles: 'white-space: nowrap;'},
