4 * Macro TOTC (Table Of Table Captions).
6 * Automatic recognition of the number of columns.
8 * Optional automatic calculation of the cell widths from the widths of the
9 first line of the cell content instead of the explicit specification with
10 the width argument. This seems to be non-trivial without a preprocessor
11 or additional external calls via .sy or .pso.
13 * Handling of pagebreaks in tables.
15 * Floating text left and/or right from tables.
17 * Converter hdtbl2html (awk, elisp, perl?); should be easy to write.
