[Tex/LaTex] Auto resize tabular row height

spacingtables

After running following code

\documentclass[10pt]{article}
\usepackage{multirow}

\begin{document}

\begin{tabular}{|l|l|l|} \hline
\multicolumn{3}{|c|}{Schedulers} \\ \hline
\multirow{3}{3cm}{Row 1. long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text } & RR & Round Robin \\
& EF & Earliest First \\
& LL & Lightest Loaded \\ \hline

\multirow{4}{*}{Row 2.} & MM & Min-Min \\ 
& MX & Max-Min \\
& DL & Dynamic Level \\ 
& RC & Relative Cost \\ \hline

\multirow{4}{*}{Row 3.} & PN & This paper \\
& ZO & Genetic Algorithm\\
& TA & Tabu search\\
& SA & Simlulated Annealing \\ \hline
\end{tabular}

\end{document}

I get this output:

What should I do to make first three rows (RR, EF and LL) accordingly higher?

Unfortunately multirow doesn't expand rows if it is bigger than the rows it is spanning. In this case changing \\ to \\[1cm] make a reasonable result. A more automatic solution is possible but harder.

\begin{tabular}{|l|l|l|} \hline
\multicolumn{3}{|c|}{Schedulers} \\ \hline
\multirow{3}{3cm}{Row 1. long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text } & RR & Round Robin \\[1cm]
& EF & Earliest First \\[1cm]
& LL & Lightest Loaded \\[1cm] \hline

\multirow{4}{*}{Row 2.} & MM & Min-Min \\ 
& MX & Max-Min \\
& DL & Dynamic Level \\ 
& RC & Relative Cost \\ \hline

\multirow{4}{*}{Row 3.} & PN & This paper \\
& ZO & Genetic Algorithm\\
& TA & Tabu search\\
& SA & Simlulated Annealing \\ \hline
\end{tabular}

[Tex/LaTex] tabu package – gaps in vertical lines

One way is to shift up the skip prior to the mid-height \tabucline with a \\[-1pt]. See below for 2nd approach.

  \begin{tabu}{ |[1pt] l | l l | l | l |[1pt] }

\hline

    &                              & \multicolumn{1}{ |[1pt] l |     }{ } &                                 & \\ \tabucline[1 pt]{1-5}

Alternately, if you want the thin line to bisect the thick line, then the approach: \\[-1pt] \tabucline[1 pt]{3-5}\\[-12.5pt]\hline works.

[Tex/LaTex] Tabular header vertical align and row height

The following MWE contains two suggestion: The first uses invisible rules to increase the row height of only the first row, while the second is an alternative approach using \toprule, \midrule and \bottomrule from the booktabs package while avoiding all vertical lines:

\documentclass{article}
\usepackage{array}
\usepackage{amsmath}
\usepackage{microtype}
\usepackage{xcolor}
\newcolumntype{M}[1]{>{\centering\arraybackslash}m{#1}}
\newcolumntype{N}{@{}m{0pt}@{}}
\newcommand{\tr}[1]{#1 &\\[22pt]}

\usepackage{booktabs}

\begin{document}
\begin{center}

\begin{tabular}{ |M{4cm}|M{4cm}|N }
  \hline
  \multicolumn{3}{|c|}{\rule{0pt}{2em}Electric Field\rule[-1em]{0pt}{2em}} \\
  \hline
  \tr{Point charge & $\vec{E} = \dfrac{1}{4 \pi \epsilon_0} \cdot \dfrac{q}{r^3} \times \vec{r}$}
  \hline
  \tr{Electric dipole & $\vec{E} = \dfrac{1}{2 \pi \epsilon_0} \cdot \dfrac{\vec{p}}{r^3}$}
  \hline
  \tr{Charged ring & $\vec{E} = \dfrac{1}{4 \pi \epsilon_0} \cdot \dfrac{q\vec{z}}{\sqrt{(r^{2}+z^{2})^3}}$}
  \hline
\end{tabular}
\end{center}

\begin{center}
\begin{tabular}{M{4cm}M{4cm}N }
  \toprule
  \multicolumn{3}{c}{\rule{0pt}{2em}Electric Field\rule[-1em]{0pt}{2em}} \\
  \midrule
  \tr{Point charge & $\vec{E} = \dfrac{1}{4 \pi \epsilon_0} \cdot \dfrac{q}{r^3} \times \vec{r}$}
  \tr{Electric dipole & $\vec{E} = \dfrac{1}{2 \pi \epsilon_0} \cdot \dfrac{\vec{p}}{r^3}$}
  \tr{Charged ring & $\vec{E} = \dfrac{1}{4 \pi \epsilon_0} \cdot \dfrac{q\vec{z}}{\sqrt{(r^{2}+z^{2})^3}}$}
  \bottomrule
\end{tabular}
\end{center}
\end{document}
