# From table to tikz

How do I go about creating the following table in tikz?

\documentclass[11pt]{article}

\usepackage{multirow}
\usepackage{geometry}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{ragged2e}
\begin{document}

\begin{table}[ht]
\centering
\begin{tabularx}{\textwidth}{cc>{\RaggedRight\arraybackslash}X>{\RaggedRight\arraybackslash}X}
\toprule
\multirow{6}{*}{Outer index 1} & Inner index 1.1 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
& Inner index 1.2 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
\midrule

• Welcome to TeX-SE! Could you please explain why you want to redraw the table in TikZ? – marmot Mar 20 at 18:06
• Thanks, @marmot I've been told that it allows for greater freedom, and since I'm having trouble doing things like vertically centering the first two columns, I thought I'd give this a try. – whoami Mar 20 at 18:08
• I would like to argue that using something like makecell will make it much more straightforward to vertically center the stuff. Of course, there are things for which you may want to use TikZ but IMHO not for that. – marmot Mar 20 at 18:34
• @marmot Wishing I had this in TikZ now: tex.stackexchange.com/questions/480602/saving-table-as-png – whoami Mar 21 at 0:27

If the effort you need for creating such tables in tabular or tabularx is 10, the effort you need for creating them in TikZ or any other drawing packages is at least 100. Anyway this is your table in a TikZ version.

Note: Customizing it is a very hard problem IMHO, because you will probably have to break all loops... Therefore, please make tables in a usual way!

• Ohh labels-programming-mode activated <3. – manooooh Mar 22 at 6:51
• Hence, "TikZ learning = 10*(Normal learning)"? :) (fixed big typo) – manooooh Mar 22 at 6:55
• @manooooh No. It is normal_way = 10 x strange_way :) (rearranged for correct order :)) – JouleV Mar 22 at 6:57
• To learn about matrices in TikZ I need 10 times more of learning a normal matrix. – manooooh Mar 22 at 7:08
