# Framed box with only bottom rules and multiple lines inside a table cell

I want to have a table with cells which have multiple lines and bottom rules.

I've tried

\begin{tabular}{cc}
\renewcommand{\arraystretch}{1.5}

Title & \parbox{18em}{\centering A very very very very very very very very very very very very very very very long title}\\\cmidrule(lr){2-2}
SubTitle & \parbox{18em}{\centering A not that long title}\\\cmidrule(lr){2-2}
\end{tabular}


which seems to work fine. But the second cmidrule is a little bit far away from the text.

My first attempt begins with

\uline\makebox[18em][c]{A very very very very very very very very very very very \\ very very very very long title}


but apparently it doesn't support breaking lines inside the box.

I also tried \parbox with \ul (in the soul package) but error throws.

I think the closest approach is combine \framebox with \parbox but I don't know how to have the bottom rule only.

• BTW, I also tried make a tcolorbox inside a cell but its nearby cell seems not vertically centered with that cell... – SXKDZ Mar 25 '19 at 1:23
• What is the reason for using parbox? Wouldn't a p type column be sufficient in order to allow for linebreaks in table cells? – leandriis Mar 25 '19 at 6:04
• @leandriis I wanna have a bottom rule of a fixed length. p works fine but I cannot have a single bottom rule only. – SXKDZ Mar 25 '19 at 6:35

Package fbox provides and optional command to fbox where you decide which sides of surrounding box are drawn.

\documentclass{article}
\usepackage{array}
\usepackage{booktabs}
\usepackage{fbox}

\begin{document}
\begin{tabular}{c>{\centering\arraybackslash}p{18em}}
\renewcommand{\arraystretch}{1.5}
Title & \fbox[b]{\parbox[t]{18em}{A very very very very very very very very very very very very very very very long title}}\\
SubTitle & \fbox[b]{A not that long title}\\
\end{tabular}

\end{document}


I'm not sure this is what you want to achieve, but \cmidrule can be shortened of a desired amount, see: How to make a \cline or \cmidrule narrower?

\documentclass{article}
\usepackage{array}
\usepackage{booktabs}

\begin{document}
\begin{tabular}{c>{\centering\arraybackslash}p{18em}}
\renewcommand{\arraystretch}{1.5}
Title & A very very very very very very very very very very very very very very very long title\\\cmidrule(lr){2-2}
SubTitle & A not that long title\\\cmidrule(l{4.5em}r{4.5em}){2-2}
\end{tabular}

\end{document}
