| Name | Description | Data Type | Default Value | Required? |
|---|---|---|---|---|
| colnum | Indicates the number of a column in the table, counting from the first logical column to the last column. | NMTOKEN | #IMPLIED | No |
| colname | Specifies the table column name in which an entry is found. | NMTOKEN | #IMPLIED | No |
| colwidth | Describes the column width. | CDATA | #IMPLIED | No |
| colsep | Column separator. A value of 0 indicates no separators; 1 indicates separators. | NMTOKEN | #IMPLIED | No |
| rowsep | Row separator. A value of 0 indicates no separators; 1 indicates separators. | NMTOKEN | #IMPLIED | No |
| align | Describes the alignment of text in a table column. Allowable values
are:
|
(left | right | center | justify | char | -dita-use-conref-target) | #IMPLIED | No |
| char | alignment character Default source for entry elements starting in this column. If character alignment is specified, the value is the single alignment character source for any implied char values for entry immediately in this column. A value of "" (the null string) means there is no aligning character. |
CDATA | #IMPLIED | No |
| charoff | horizontal offset of alignment character when align=char Default source for entry elements starting in this column. For character alignment on an entry in the column, horizontal character offset is the percent of the current column width to the left of the (left edge of the) alignment character. This value should be number, greater than 0 and less than or equal to 100. |
NMTOKEN | #IMPLIED | No |
| base | A generic attribute that has no specific purpose, but is intended to act as a base for specialized attributes that have a simple value syntax like the conditional processing attributes (one or more alphanumeric values separated by whitespace). The attribute takes a space delimited set of values. However, when acting as a container for generalized attributes, the content model will be more complex; that model is documented in the "attribute generalization" section of the DITA architectural specification. | CDATA | #IMPLIED | No |
| %id-atts; (id, conref) | A set of related attributes, described at %id-atts; | parameter entity | PE not applicable | Not applicable |
| %localization-atts; (translate, xml:lang, dir) | A set of related attributes, described at %localization-atts;. | parameter entity | PE not applicable | Not applicable |
| %global-atts; (xtrf, xtrc) | A set of related attributes, described at %global-atts; | parameter entity | PE not applicable | Not applicable |
| class | Common attribute described in Other common DITA attributes. |
