Summaries a Data Column Group in a Data Table - Web Experience Toolkit (WET)

Attention: Since WET 3.0.2

The default behaviour regarding the subsequent group has been changed because of backward compatibility issue and because of some use case. The option "hassum" is now required to apply this technique.

Note: Table Source Code Example

Id/Headers attribute, colgroup element and col element was omited intentionally for clarity.

Description of Technique

The objective of this technique is to separate the data column group with their associative data summary column group. This concept is similar as the "tfoot" definition and the row group summary.

A data table need to have column header cell and have the option "hassum" set to define a column summary group.

The column group level is calculated based on the highest row that would identify the data group with the summary group. The level of the column data group is calculated based on their associate column summary group.

By default, With the option "hassum" set, if there is only one row of column header cell, the first data column group is at level 1. If a table contain for example 3 group (excluding the column header group), the first one is a data group at level 1, the seconde one is a summary group at level 1 and the third one is a summary group at level 0. No other group can exist after the summary column group at level 0 is reached.

For the best tabular data representation is recommended to be consistant in the column heading structure.

A column cell heading that cover a data group and a summary group is called a group header cell. Each group header cell start on the begin of a column group and end to his associated summary or before.

Normally a data column group is larger (Contain more cell) than his associated summary group
