Hi, the method below alert a notice

function set_cell_attribute($name,$attr,$value){ if (!$this->cell_attrs[$name]) $this->cell_attrs[$name]=array(); $this->cell_attrs[$name][$attr]=$value; }
And I changes !$this->cell_attrs[$name] to !isset($this->cell_attrs[$name])

Thanks for helpful info, we will add the similar fix in the main codebase.
