# LyX table: “Misplaced \noalign” error in colored multicolumn row

I found out how to color table cells/columns/rows thanks to the answers here and here.

I followed the examples in the documentation. In the preamble, I put:

``````\usepackage{colortbl}
\definecolor{lightgray}{gray}{0.9}
``````

And at the beginning of the row, I put a TeX box with:

`\rowcolor{lightgray}`

It does work, i.e. the table is generated with the desired color, but LyX always displays a bunch of "Misplaced `\noalign`" errors.

Thus, I needed to use `\cellcolor{lightgray}` instead of `\rowcolor{lightgray}`.
