26.2.1.2 Using header cells to define column groups

Mif2Go refers to a column-header cell with a group attribute as a ColGroup cell. To make a header cell a ColGroup cell, include in it one of the following:

a paragraph that is in a format you have designated [HTMLParaStyles] ColGroup
(see §26.2.2 Using paragraph formats for table-cell attributes)

a CellGroup marker that you have given content col
(see §26.2.4 Assigning table-cell attribute values with custom markers).

When you designate a header cell as a ColGroup cell, the effect of that property depends on which method you specify for table columns:

scope automatically specifies the following:

[Tables]ColGroupElements=Yes
(ColGroup cell starts a new <colgroup> element)

scope="colgroup" in the ColGroup cell
(ColGroup cell affects all other cells subsumed by its <colgroup>)

id/headers automatically specifies the following:

[Tables]ColGroupIDs=Yes
(ColGroup cell gets id="groupN", dependent cells get headers="groupN")

See §27.5.1 Understanding how the ColGroup property works for more information.
