##### 33.4.9.3 Maintaining the width of table columns via relative sizing

You can specify relative column widths for a table to override the widths specified in your DITA document, or if no widths are specified in DITA. Otherwise, use one of the settings described in §33.4.9.1 Specifying a method for determining table column widths, such as:

[Tables]
TableSizing = Percent

Suppose you have specified the following settings as defaults for all tables in your document:

[Tables]
TableSizing = Adaptive
Border = 1
Spacing = 0
Padding = 4

And suppose for one particular table format, TwoCol, you want relative column widths:

[TableSizing]
TwoCol = Percent

This setting would make the width of each column in each TwoCol table a percent of the width of that particular table; but the setting would not specify the percentage.

If what you really want is for each TwoCol table to have columns of equal width, instead you would specify:

[TableCellAttributes]
TwoCol = width="50%"

Naturally, this setting works only if all TwoCol tables have exactly two columns.

To set the width of the table itself, you could add:

[TableAttributes]
TwoCol = width="100%"

This setting would eliminate your [Tables] settings for border, cellpadding, and cellspacing; so you would have to add them to the attribute list for TwoCol tables:

[TableAttributes]
TwoCol = width="100%" border="1" cellpadding="4" cellspacing="0"

See §33.4.2 Overriding attributes for selected tables.
