Table Cell Alignment Character (NISO JATS table model)
The character to be used in horizontal alignment of the contents of an entry in a
table. The content of a table data or table header element is to be aligned horizontally based on the character named in this
attribute, for example, alignment on a period for decimal alignment or on an equal sign for alignment of variables. (This
attribute is based on and
intended to be converted easily to the XHMTL char attribute.)
|Text, numbers, or special characters
||When used in conjunction with align="char", the contents of the table entry are aligned relative to the character specified by this attribute.
|Restriction: @char is an optional attribute; there is no default.
