Use the wjStyle binding together with the wjFlexGridColumn binding to provide conditional formatting to column cells. For example:

<div data-bind="wjFlexGridColumn: {
        header: 'Change',
        binding: 'changePercent',
        format: 'p2',
        width: '*'
        },
        wjStyle: { color: getAmountColor($item().change) }"></div>

The wjStyle uses the same syntax as the native KnockoutJS style binding. In addition to the view model properties, the following observable variables are available in binding expressions:

$item

References the item that is bound to the current row.

$row

The row index.

$col

The column index.
