Why does adding color to a table row increase the height?

Question

I'm trying to make a beamer slide containing a table with the text in a row styled in a different color. However, the row's height increases when colored, as opposed to the default. The same problem occurs if I use the \rowfont command. How do I correct this?

\PassOptionsToPackage{table}{xcolor}
\documentclass[compress]{beamer}

\begin{document}
\begin{frame}
    Example 1
    \rowcolors{1}{gray!30}{blue!30}
    \begin{tabular}{|p{0.5\textwidth}|}
        \hline
        \color{blue}{Foo} \\
        Bar\\
        Baz\\
        \hline
    \end{tabular}\\[1in]

    Example 2
    \rowcolors{1}{gray!30}{blue!30}
    \begin{tabular}{|p{0.5\textwidth}|}
        \hline
        Foo \\
        Bar\\
        Baz\\
        \hline
    \end{tabular}
\end{frame}
\end{document}

I want the table to look like "Example 2", but with the row text colored as in "Example 1".

Answer 1

Use textcolor:

\PassOptionsToPackage{table}{xcolor}
\documentclass[compress]{beamer}

\begin{document}
\begin{frame}

    Example 1
    \rowcolors{1}{gray!30}{blue!30}
    \begin{tabular}{|p{0.5\textwidth}|}
        \hline
        \textcolor{blue}{Foo} \\
        Bar\\
        Baz\\
        \hline
    \end{tabular}\\[1in]

    Example 2
    \rowcolors{1}{gray!30}{blue!30}
    \begin{tabular}{|p{0.5\textwidth}|}
        \hline
        Foo \\
        Bar\\
        Baz\\
        \hline
    \end{tabular}
\end{frame}
\end{document}

Answer 2

With {NiceTabular} of nicematrix, you have directly the expected output.

\documentclass[compress]{beamer}
\usepackage{nicematrix}

\begin{document}
\begin{frame}
\begin{NiceTabular}{|p{0.5\textwidth}|}
\CodeBefore
  \rowcolors{1}{gray!30}{blue!30}
\Body
  \hline
  \color{blue}{Foo} \\
  Bar\\
  Baz\\
  \hline
\end{NiceTabular}
\end{frame}
\end{document}

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