LaTeX tip: one counter for tables and figures

To use a single counter for tables and figures in the LaTeX document

\makeatletter
\renewcommand*{\thetable}{\arabic{table}}
\renewcommand*{\thefigure}{\arabic{figure}}
\let\c@table\c@figure
\makeatother  

in the preamble of the document. One can test it using dummy text, thanks to blindtext package, i.e.

\usepackage[english]{babel}
\usepackage{blindtext}

for the preamble and

\blindtext
\Blindtext

in the main body of the document to produce a paragraph or two of the dummy text.
