How can I solve this problem when I write a lot?

Question

In this fantastic post of @percusse: https://tex.stackexchange.com/a/67736/159009

I have problems when I write so much words, like this:

\documentclass{standalone}
\usepackage{tikz}
\usepackage{PTSansNarrow}
\usepackage[T1]{fontenc}

\usetikzlibrary{matrix}

\begin{document}
\begin{tikzpicture}
\clip node (m) [matrix,matrix of nodes,
fill=black!20,inner sep=0pt,
nodes in empty cells,
nodes={minimum height=1cm,minimum width=2.6cm,anchor=center,outer sep=0,font=\sffamily},
row 1/.style={nodes={fill=black,text=white}},
column 1/.style={nodes={fill=gray,text=white,align=right,text width=2.5cm,text depth=0.5ex}},
column 2/.style={text width=4cm,align=center,every even row/.style={nodes={fill=white}}},
column 3/.style={text width=3cm,align=center,every even row/.style={nodes={fill=white}},},
row 1 column 1/.style={nodes={fill=gray}},
prefix after command={[rounded corners=4mm] (m.north east) rectangle (m.south west)}
] {
    & Enterprise SAN                     & ioDrive \\

Produce this problem (the structure breaks):

How can I solve it?

(I haven't written this in the commentary because is very difficult to explain this in a commentary).

Answer 1

You can adjust the height of row two by adding the style row 2/.style={nodes={minimum height=2cm}}. I also replaced text depth=0.5ex by inner sep=.35em in column 1.

\documentclass[border=7mm]{standalone}
\usepackage{tikz}
\usepackage{PTSansNarrow}
\usepackage[T1]{fontenc}

\usetikzlibrary{matrix}

\begin{document}
\begin{tikzpicture}
\clip node (m) [matrix,matrix of nodes,
fill=black!20,inner sep=0pt,
nodes in empty cells,
nodes={minimum height=1cm,minimum width=2.6cm,anchor=center,outer sep=0,font=\sffamily},
row 1/.style={nodes={fill=black,text=white}},
row 2/.style={nodes={minimum height=2cm}}, % <-- added to adjust the height of row 2
column 1/.style={nodes={fill=gray,text=white,align=right,text width=2.5cm,inner sep=.35em}},
column 2/.style={text width=4cm,align=center,every even row/.style={nodes={fill=white}}},
column 3/.style={text width=3cm,align=center,every even row/.style={nodes={fill=white}}},
row 1 column 1/.style={nodes={fill=gray}},
deeper/.style={text=red},
prefix after command={[rounded corners=4mm] (m.north east) rectangle (m.south west)}
