### Table lines starting with square bracket

this one does not compile:

\documentclass{article}
\begin{document}
\begin{tabular}{ll}
a & b \\
[c] & d \\
\end{tabular}
\end{document}

if required, one can specify the vertical gap between lines in a table using
\\[len]

LaTeX removed the newline and whitespace to interpret the table as having a \\[c] entry, and there exists no length "c".

So the solution is to write the initial square bracket into curly braces. This way it is not interpreted as the beginning of the optional argument of the newline command.

\documentclass{article}
\begin{document}
\begin{tabular}{ll}
a & b \\
{[}c] & d \\
\end{tabular}
\end{document}

Thanks to Werner Grundlingh for showing me the problem source.

You may simplify use \relax

a & b \\ \relax
[c] & d

Very useful when using with XeLatex especially when we use below syntax for non-english based Song latex package
\begin{tabular}
\[గా గ గా మ గ]
\end{tabular}

This solution is helpful as this is required in cases for typesetting carnatic music documents

I found that prepending a tilde works as well.

a & b\\
~[c] & d

title results in small space in front of [string]
