# side by side table

I am trying to figure out how to put these tables side by side (or at least in a proper form)

\begin{table}
\caption{Initial measurement of photoresist step heights for $15$ and $30$ wafers ($A^\circ$)}
\label{tab:fonts}
\begin{center}
\begin{minipage}[b]{0.33\linewidth}\centering
\begin{tabular}{|l|l|} %% this creates two columns

• Not directly related to your posting, but relevant for good typography: I assume that $A^\circ$ is supposed to denote "angstrom". If that's the case, you really should write it as "\AA" in text mode: the "ring" belongs on top of the uprightshape "A", not to the side of a slanted "A".

The floatrow package lets you easily align captions by their top lines. No need to add invisible rules to add some padding to the rows: with the cellspace package, you can define minimal vertical spacing between a row and the above and below cells.

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[showframe]{geometry}
\usepackage{caption, floatrow,cellspace}
\setlength\cellspacetoplimit{5pt}

\DeclareFloatSeparators{mysep}{\hskip1.6em}
\begin{document}
\captionsetup{font=footnotesize}
\floatsetup{floatrowsep=mysep, capposition=TOP, captionskip =1.5ex}
\begin{table}[!hbt]

• @Mico: Oh! yes, you're right. I've changed it. Thanks! Feb 25, 2016 at 9:56

Do you like to have something like this:

In your MWE the role of \rule[-1ex]{0pt}{3.5ex} is replaced it by \renewcommand{\arraystretch}{1.3}, which made similar height of cells as it was before. From question is not clear to me what you like to obtain with mix of "mini pages", "center" environments and use of \centering. I clear all this codes and form three minipages in which are tables centered by \centering command.

Beside this I add package siunitx and use its S column type for nicer typing of numbers in your tables.

Note: I didn't bother with caption formatting.

Addendum: Lets do the do-it-for-me service for added second part of question (I do this since I'm happy that after few hour of repairing my MikTeX installation it works again as desired ... ). The code is:

    \begin{table}
\centering
\renewcommand{\arraystretch}{1.3}
\begin{minipage}[b]{0.33\linewidth}\centering
\caption{Measurement of oxide thickness for blank wafer before etch (pre etch)} \label{tab:1}
\label{tab:fonts}
\begin{tabular}{|l|S[table-format=5.0,
table-space-text-post=\si{\angstrom}]<{\si{\angstrom}\ }|}
\hline
center  &   5114    \\  \hline
top     &   5236    \\  \hline
right   &   5196    \\  \hline
bottom  &   5156    \\  \hline
left    &   5211    \\  \hline
\end{tabular}
\end{minipage}
\hfil
\begin{minipage}[b]{0.33\linewidth}\centering
\caption{Measurement of oxide thickness for blank wafer after etch (post etch)} \label{tab:2}
\label{tab:fonts}
\begin{tabular}{|l|S[table-format=5.0,
table-space-text-post=\si{\angstrom}]<{\si{\angstrom}\ }|}
\hline
center  &   3088    \\  \hline
top     &   3154    \\  \hline
right   &   3133    \\  \hline
bottom  &   3043    \\  \hline
left    &   3112    \\ \hline
\end{tabular}
\end{minipage}
\end{table}


In above code I assume, that $A^\circ$ mean unit Angstrom. I use standardizired notation for it as defined insiunitx package (this was not considered in the first table).

Result:

• @ zarko I do not know where I have an error, but see my original question - second part is added. I tried to put them in side by side as well. Feb 25, 2016 at 2:04
• @Mohammad , second part of your questions contain the same errors as the first part, which is corrected in my answer. You need to reformat its code on the same way as I do for your first part (all should be in one table environment, erase all \begin{center} andend{center}, between minipages` cannot be empty lines ..). Please try to make analysis of my answer and do the same. Temporary I can't help you since just now I try to reinstall my MikTeX ... Feb 25, 2016 at 2:51
• @Mohammad, I format the second part of your question. Feb 25, 2016 at 4:38
• @ Zarko, thank you for very informative answer. I could easily practice that. if you interested to question, please upvote that. Feb 25, 2016 at 5:12
