tabbing ¶Synopsis:
\begin{tabbing}
row1-col1 \= row1-col2 ... \\
row2-col1 \> row2-col2 ... \\
...
\end{tabbing}
Align text in columns, by setting tab stops and tabbing to them much
as is done on a typewriter. This environment is less often used than
the tabular (see tabular) and array (see array)
environments, because in those the width of each column need not be
known in advance.
