# How to display contents of a tree grid in a latex table

I am working on displaying a nested bill of material in tree grid in a latex document.

Is there a package available that can help with this?

A short example of my current table

\begin{table}[h]
\centering
\begin{tabular}{| l | l | c | c | r | r | }
\hline
Item & Description & Quantity & Units & Cost & Extended \\
\hline
\rowcolor{lightgray} Pulley &  Pulley & 1.0 &  Each &  15136.8 &  15136.8 \\
\rowcolor{lightgray} Shell &  996.5 ID x 1856 Plate 4140 32mm & 1.0 &  Each &  3516.04 &      3516.04 \\
\hspace{0.3cm}  PM00000019 &  Weld MIG & 25.6763 &  Kg &  1.2 &  30.81 \\
\hspace{0.3cm}  PM00000012 &  Weld MIG & 1.0135 &  Hr &  90.0 &  91.22 \\

\hline
\end{tabular}
\caption{Bill of Material}
\label{tab:my_label}
\end{table}

• Welcome to TeX.SX. Questions about how to draw specific graphics that just post an image of the desired result are really not reasonable questions to ask on the site. Please post a minimal compilable document showing that you've tried to produce the image and then people will be happy to help you with any specific problems you may have. See minimal working example (MWE) for what needs to go into such a document. – cfr Feb 23 '15 at 0:38
• What is the problem, exactly? I mean, 'yes, there is a package' but it is hard to know where the gaps in your knowledge are without seeing what you've got so far. So it is well nigh impossible to say anything useful. (Without just drawing the whole thing for you, of course.) – cfr Feb 23 '15 at 0:40
• Hi. Clearly it's not difficult to display a table with latex. The question really is there an easy way to display a tree structure as shown in the Component ID column. – Andrew Feb 23 '15 at 0:42
• Then why don't you post some code for the easy bit so people who are interested can help you with the hard bit? – cfr Feb 23 '15 at 0:44
• Please post complete code i.e. a compilable document. This is much more useful than a mere fragment. – cfr Feb 23 '15 at 17:17

You can try with tikzmark library:

\documentclass{article}
\usepackage{colortbl}
\usepackage{xcolor}
\usepackage{tikz}
\usetikzlibrary{tikzmark}

\begin{document}
