<TeXmacs> supports a few special notations for applying operations on all <TeXmacs> supports a few special notations for applying operations on all
cells in a subtable. For instance, cells in a subtable. For instance, as in <name|Excel>, one may use the
notation <samp|c3:d5> for indicating all cells <samp|c3>, <samp|c4>,
<samp|c5>, <samp|d3>, <samp|d4>, <samp|d5> in the block from <samp|c3> to
<samp|d5>. An alternative notation <cell-commas> for <samp|:> can be
entered by typing <key|, ,>. In a similar way, one may enter the special
notation <cell-plusses> by typing <key|+ +>. For instance,
<samp|c3<cell-plusses>d5> stands for the sum of all cells between <samp|c3>
and <samp|d5>.
<\example>
The figure below shows an example on how to use taking sums of cells.
Notice that empty cells count for zero.

Notice that copying and pasting of subtables works in the same way as for
ordinary tables, with the additional features that the names of the cells
and references to cells in the formulas are renumbered automatically.
Similarly, automatic renumbering is used when inserting new columns or
rows, or when removing existing columns or rows.
