public class Colgroup<T extends Colgroup<T>> extends StyledElement<T>
Represents an HTML <colgroup> element for grouping table columns.

The Colgroup element specifies a group of one or more columns in a table for formatting. It must be a child of a Table element, after any <caption> elements and before any <thead>, <tbody>, <tfoot>, and <tr> elements.

The <colgroup> element restricts its content to Col elements only. Use addCol(Col) to add column definitions.

Features:

  • Groups table columns for styling
  • Can contain col elements
  • Span attribute for simple column grouping
  • Useful for applying styles to column groups

Usage:


 // Simple column group with span
 Colgroup colgroup = new Colgroup(3);

 // Column group with individual col elements
 Colgroup colgroup = new Colgroup();
 colgroup.addCol(new Col());
 colgroup.addCol(new Col());
