\tikzmarkinbefore first column and row element and\tikzmarkendafter last column and row element. – Ignasi Oct 19 '15 at 08:33I tried it, but it does not work. When I change \tikzmarkin and \tikzmarkend, the code highlights all cells between the first and the last selected elements (by rows). what I want is to highlight just a column. Thanks once again. Best, T.
