# Help with Tabularx

Hello I have this table

    \begin{tabularx}{\textwidth}{ |X|X|X|X|X| }
\hline
$n$ & 50 & 100 & 200  & 500 \\
\hline
$t_{rel}$  & 250  & 1013  & 4052 & 25330  \\
\hline
$\tilde t_{rel}$  & 29.43 & 58.3  & 124.4 & 250 \\
\hline
\end{tabularx}


for different values of $n$ you get different values of $t_{rel}$ and $\tilde t_{rel}$. The problem is that in the pdf it doesn't look good at all, you can't even see the "tilde" sign for $\tilde t_{rel}$. I am not familiar with tabulax Can anyone help me?

• I would not use tabularx for tables of data like this just use a normal tabular. The setting of the entries is unrelated to the table \tilde{t}{\mathrm{rel}} should make a t with a tilde accent and subscript rel, do you not see that in your output? (note it should be \mathrm{rel} not rel unless you mean the product r*e*l) Oct 13, 2017 at 15:57

Use booktabs for your presentation:

\documentclass{article}

\usepackage{booktabs,siunitx}

\begin{document}

\begin{tabular}{ S[table-format=3] S[table-format=5] S[table-format=3.1,table-auto-round] }
\toprule
{$n$} & {$t_{\mathrm{rel}}$} & {$\tilde{t}_{\mathrm{rel}}$} \\
\midrule
50 & 250 & 29.43 \\
100 & 1013 & 58.3 \\
200 & 4052 & 124.4 \\
500 & 25330 & 250.0 \\
\bottomrule
\end{tabular}

\end{document}


The horizontal alignment of numbers make for an easier gauge on their respective magnitudes.

I would typeset this table as follows:

\documentclass[]{article}

\usepackage{siunitx}
\usepackage{booktabs}

\begin{document}
\begin{tabular}{l S[table-format=3.2] *2{S[table-format=4.1]} S[table-format=5]}
\toprule
$n$ & 50 & 100 & 200  & 500 \\
$t_{rel}$  & 250  & 1013  & 4052 & 25330  \\
$\tilde t_{rel}$  & 29.43 & 58.3  & 124.4 & 250 \\
\bottomrule
\end{tabular}
\end{document}
