Hi Keerthiga,
With both our Table and DataTables widgets, there's the "formatValue" property for each column where you could customize a column's display value. For example:
Table::create(array(
"dataStore"=>$this->dataStore("data_sample"),
"columns"=>array(
"item",
"total"=>array(
"formatValue"=>function($value, $row)
{
return (($value>1000)?"<i class='fa fa-thumbs-o-up text-success'></i>":"<i class='fa fa-thumbs-o-down text-danger'></i>").' $'.number_format($value);
}
)
)
));
Just change the formatValue's function to modify your returned value. Let us know if this helps solve your problem. Thanks!
