charoff Table Character Offset (NISO JATS table model)
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. (This attribute is based on and intended to be converted easily to the XHTML charoff attribute.)
Alignment on a particular character requires that three attributes be set in the document:
- The @align attribute value is set to the word “char”.
- The @char attribute value is set to the actual character to use for the aligning, for example, a decimal point, “.”.
- 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”.

|Restriction||@charoff is an optional attribute; there is no default.|
