When tex builds the table, since it finds nothing in the last column, it doesn't consider it, so \cline{2-6} finds itself in trouble and the result is what you observe.I want to draw a double cline in a table where the first column is multirow with double \\hline i can draw a full double horizontal line but double \\cline{i-j} seems to have the same effect with siI am using multiple instantiations of \multicolumn and \multirow, and i was wondering if it were possible to use a discontinuous \cline so as not to strike though the o's in the code above.How to write \\clines (or \\hhline) in colored tables so that the color of the cell does not hide the line?Here are two solutions but neither of them works fine.
