Ensure Tab skips a whole series of hidden columns

I have a dhtmlx Grid, at the end of each row, I have a series of hidden columns (they are not read-only).

How can I make sure (without using onTab) that hidden columns are not tabbed into?

You may use the setEditableTabOnly() method to tab only tthrough the editable cells :
docs.dhtmlx.com/api__dhtmlxgrid_ … bonly.html

or you may set your own order of the tabbing and skip your hidden columns:
docs.dhtmlx.com/api__dhtmlxgrid_settaborder.html

also it is not available to tab to the column that is hidden:
