I'm having trouble aligning text inside a TikZ table. It currently just centres the middle letter, despite the align=left.
I also tried using:
row 1/.style={nodes={align=left}}
(as suggested in Creating table using TikZ matrix)

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix,positioning}
\usetikzlibrary{calc}
\usetikzlibrary{decorations.pathmorphing}
\tikzset
{
table/.style={matrix of nodes,
row sep=-\pgflinewidth,
column sep=-\pgflinewidth,
nodes={rectangle,
draw=black,
text width=2ex,
align=left,
minimum width=1.5cm
},
text depth=0.25ex,
text height=2ex,
nodes in empty cells
},
texto/.style={font=\footnotesize\sffamily},
title/.style={font=\small\sffamily},
my top text/.style={font=\small\sffamily},
my bottom text/.style={font=\sffamily\footnotesize}
}
\newcommand\CellText[2]{%
\node[texto,left=of mat#1,anchor=east]
at (mat#1.west)
{#2};
}
\newcommand\SlText[2]{\node[my top text,anchor=base] at ($(mat#1.north)+(0,1.0ex)$) {#2};}
\newcommand\SIundertext[2]{\node[my bottom text,anchor=base] at ($(mat#1.south west)-(0,2.0ex)$) {#2};}
\newcommand\RowTitle[2]{%
\node[title,left=6.3cm of mat#1,anchor=west]
at (mat#1.north west)
{#2};
}
\begin{document}
\begin{tikzpicture}[node distance=0pt and 0.5cm]
\matrix[table] (mat11) { 1,53& |[draw=none,alias=gap A]| & 22 & 22 & 22,24 & |[draw=none,alias=gap B]| & 1 \\ };
\foreach \x/\y in {1/$0$,

\foreach \x in {A,B}{

\node[my top text,anchor=base east] at ($(mat11-1-1.north west)-(2ex,0)+(0,1.0ex)$) {Bin};
\node[my bottom text,anchor=base east] at ($(mat11-1-1.south west)-(2ex,0)-(0,2.0ex)$) {Time};
\node[title,anchor=east] at ($(mat11-1-1.west)-(1.5cm,0)$) {Vehicle $k$};

Previous question where I was very kindly helped to this point can be found in TikZ table with floating labels + time discontinuity.

minimum widthis only the width of the node (includinginner xseps and the width of the text box),text widthis the actual with of the text box. Thealignkey changes the alignment of text inside the text box not the alignment of the text box inside the node. – Qrrbrbirlbel Sep 22 '13 at 13:07
