-% Adjusting the height using "\vstrut" is done by trial and error.
-% While a vertical phantom box would provide a good result,
-% for example "\vphantom{\bar{t}}" in the previous square root,
-% it's not obvious to know what to put in the phantom box.
-% Moreover, "\vstrut" allows a finer tuning.
+% \DescribeMacro{\cstrut}
+% The "\cstrut" macro is a alternative of "\vstrut" that adds a symmetric strut in height
+% and depth relative to the mathematical center line, which is halfway the height of an `x'.
+% It takes a single parameter "\cstrut"\marg{height}.
+% It's useful in \texttt{array} environments as it maintains
+% the mathematical axis at the center of the cell with \meta{height}
+% above and under.
%
% In a table, using
% "\renewcommand{\arraystretch}"\marg{stretch}
% allows you to increase the height of all rows, but it
-% has a global effect, whereas "\vstrut" allows to adjust the height of each row individually,
