Ta-LT

Enter 50 a and a few b like so"  then select the first colum and set the filter like so:  then click OK and it's all gone ...

And are you sure this is going to work?  If the exceptRowTotalHeight is bigger than the canvas' height, not a single row is ever gonna show.

And all the t && t.text ? t.text : ""; needs to be changed to t && t.text != null ? t.text : ""; otherwise all 0s bind by code...

I'm not using freeze.
