charoff

Table Character Offset (XHTML table model)

Definition

Horizontal offset from the alignment character specified by the char attribute; the percent of the current column width to the left of the (left edge of the) alignment character.

See W3C documentation for the XHTML table model.

Remarks

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”.
