Hello,

I was trying to get an average to be calculated for a column in the table widget using grouping function. Adding

    "grouping"=>array(
        "agent"=>array(
            "calculate"=>array(
                "{commPaidSum}"=>array("sum","commPaid"),
            	"{CommissAvg}"=>array("avg","AgentCommPerc"),
            	"{revenueSum}"=>array("sum","revenue"),
            ),

did not give me the result expected. After looking for the problem root, I discovered a bug in your code at core/src/widgets/koolphp/Table.php at line 238 it is

                        if (in_array($method, array("sum", "count", "min", "max", "mode"))) {

and should be including the "avg":

                        if (in_array($method, array("sum", "count", "min", "max", "mode", "avg"))) {

Please correct it. Kind Regards!

:-)
