 PSML elements

<col>

Summary

The <col> element defines a column in a table.

It is an optional element akin to the HTML's <col> or docbook <colspec> elements.

It can be used to specify some properties such as width, horizontal alignment or role to a column, or a range of columns, so that all cells belonging to that column inherit these properties.

A column can also be defined as a header column, meaning that all the cells in the column are considered to be header cells.

@align

The horizontal alignment of text within cells belonging to that column (may not be supported by all export formats).

Possible values are:

  • center
  • justify
  • left
  • right

@part

The part of the table the column belongs to.

For example, if a <col> element includes a @part attribute set toheader, all cells in that column are considered to be header cells.

@role

A role for the table which can be used for formatting.

@span

The number of columns this definition extends to.

Using @span is deprecated as it can cause errors when editing tables via the user interface. Instead, define all columns separately to apply the same formatting.

@width

The width of column in pixels or percent (pixels if no px or % suffix).
