Hi zenon,

You may use "formatValue' for date columns:

Table::create(array(
    "columns"=>array(
        "date"=>array(
            "label"=>"",
            "formatValue"=>function($value){
                return "Date: ".$value;
            }
        )
    )
))

The formatValue can be set function. This function will receive the date as parameter (stored in $value variable). You will return any display for this column. Please format the date if you need to.
