Table Cell Alignment Character (XHTML table model; OASIS table model)


See documentation for the HTML 4.0 (XHTML) table model or OASIS (CALS) Exchange table model (XML version), dependent upon element involved.

Specification of 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 horizontally aligned based on the character named in this attribute, for example, a period for decimal alignment or an equal sign for alignment of variables


Alignment on a particular character requires that three attributes be set in the document:

  1. The align attribute value is set to the word “char”.
  2. The char attribute value is set to the actual character to use for the aligning, for example, a decimal point, “.”.
  3. The charoff attribute value is set to the percent of the current column width to the left of the (left edge of the) alignment character, for example, “30”.
