The column element defines one column within a grid. If an element references a column that does not exist, then BIRT creates the column implicitly as a variable-width column.
The developer defines columns to aid in report layout. Each column has the following properties:
Each column definition element defines one or more adjacent columns in the table. The column definition section is optional. If not provided, BIRT ERD computes the set of columns from the table bands, as described below.
The number of adjacent columns described by this element.

A table often has a series of columns with an identical format. For example, an accounting report may display debits in one column and credits in another. This property is a convenience to allow defining the column attributes once, and apply them to a set of adjacent columns.

Column provides many style properties. The style properties are defined in the ROM Styles Specification. A column can inherit its style properties from a parent element, from a named style, or from a style that identifies the context in which the item appears. This property provides the name of the shared style to use.
This item can also set the value of style properties. Properties set on this element "override" those inherited from a parent element or a shared style.

The width of the column. The width can be omitted. If so, BIRT automatically computes the width based on the content of the table.
Widths can be absolute (1 inch) or relative (20%). Widths are entered using the CSS dimension system. See the discussion of Dimensions in the ROM Overview Specification for details.
