How do I prevent \cellcolor from over effect of \hline

Question

I'm trying to add HTML code based color to my table, like so:

\usepackage[table]{xcolor}

\begin{tabular}{ |>{\columncolor[HTML]{F2FAF8}}c| p{11cm} |}
    \hline
CELL 1 & CELL 2\\ \hline
CELL 1 & CELL 2\\ \hline
CELL 1 & CELL 2\\ \hline
 \end{tabular}

however, the cells seem to overflow on top of the \hline, like so:

Bad table!

How do I prevent this from happening?

UPDATE in response to comments:

I tried:

\setlength{\arrayrulewidth}{1pt}
\begin{tabular}{ |>{\columncolor[HTML]{F2FAF8}}c| p{11cm} |}
    \hline
CELL 1 & CELL 2\\ \hline
CELL 1 & CELL 2\\ \hline
CELL 1 & CELL 2\\ \hline
 \end{tabular}

no go:

It doesn't really happen (I claim:-) try zooming in or out in your pdf viewer. You could increase the length \arrayrulewidth to have slightly less fragile lines. — David Carlisle, May 14 '13 at 13:33
Seems to work fine when I compile with your minimal example. Are there perhaps other packages you're loading which might be interacting here? — A.Ellett, May 14 '13 at 13:33
@A.Ellett I don't think so. My preamble consists of: \documentclass[12pt]{article} \pagestyle{empty} \usepackage[utf8]{inputenc} — blueberryfields, May 14 '13 at 14:18

I claim this is a problem with the dvi driver bleeding the coloured panels too far, but I see the same with dvipng You can compensate by over-printing an uncoloured table over the top so the rules are on top of the colour not adjacent.

Compare

and

\documentclass{standalone}

\usepackage[table]{xcolor}

\begin{document}


\def\foo#1{\begin{tabular}{ |>{#1}c| p{11cm} |}
    \hline
CELL 1 & CELL 2\\ \hline
CELL 1 & CELL 2\\ \hline
CELL 1 & CELL 2\\ \hline
 \end{tabular}}


\foo{\columncolor[HTML]{F2FAF8}}\llap{\foo{}}

\end{document}

The text looks bolder though. – Wok Jan 27 '16 at 10:04

@Wok yes it would be better to arrange that the overprint version uses phantom for the text so just has the rules – David Carlisle Jan 27 '16 at 10:30

The package nicematrix has tools which has been designed to address that kind of problem. With that package, the rules won't seem to disappear in some PDF viewers at some levels of zoom.

\documentclass{article}
\usepackage{nicematrix,xcolor}
\begin{document}
\begin{NiceTabular}{>{\columncolor[HTML]{F2FAF8}}cp{11cm}}[color-inside,hvlines]
CELL 1 & CELL 2\ 
CELL 1 & CELL 2\ 
CELL 1 & CELL 2\ 
\end{NiceTabular}
\end{document}

You need several compilations (because nicematrix uses PGF/Tikz nodes under the hood).
