row height

How to change row height of tables in LaTeX.

Problem

The height of cell could be not high enough for some reasons.

Solution

If you just want to change height of all rows, just wrote \renewcommand{\arraystretch}{parameter} before this table.

Example

\documentclass{article}
\begin{document}

\begin{tabular}{|r|c|l|}
\hline 
A & B & C \\
\hline 
1 & 2 & 3 \\
\hline 
\end{tabular}
\renewcommand{\arraystretch}{2}
\begin{tabular}{|r|c|l|}
\hline 
A & B & C \\
\hline 
1 & 2 & 3 \\
\hline 
\end{tabular}
\renewcommand{\arraystretch}{1}
\end{document}
Output:

Hint

After using this renewcommand, you should change the size back to 1 by \renewcommand{\arraystretch}{1}. If you do not change it back every following array and table would become an icrease in height.

changing one row

To change only one particular row you could use the command \rule with a width of zero and the height you want as parameter, for example \rule{0pt}{25pt}

example 2

\documentclass{article}
\begin{document}

\begin{tabular}{|r|c|l|}
\hline 
A & B & C \\
\hline 
1 & 2 & 3 \\
\hline 
\end{tabular}
\begin{tabular}{|r|c|l|}
\hline 
A & B & C \\
\hline 
\rule{0pt}{25pt}1 & 2 & 3 \\
\hline 
\end{tabular}
\end{document}
Output:
