You can do this by setting it in the column definition as follows:
columns: [
{ text: 'First Name', datafield: 'firstname', width: 100 },
{ text: 'Last Name', datafield: 'lastname', width: 100 },
{ text: 'Product', datafield: 'productname', width: 180 },
{ text: 'Quantity', datafield: 'quantity', width: 80, cellsalign: 'right' },
{ text: 'Unit Price', datafield: 'price', width: 90, cellsalign: 'right', cellsformat: 'c2' },
{ text: 'Total', datafield: 'total', minwidth: 100, resizable: false, width: 'auto', cellsalign: 'right', cellsformat: 'c2' }
]
