@NullMarked
@Tag("col")
public class TableColumn
extends HtmlComponent
implements TableColumnSpan

Component representing a <col> element ? a column (or range of columns, via TableColumnSpan.setSpan(int)) inside a TableColumnGroup. Use it to apply column-wide styling without repeating it on every cell: a class or id on a <col> can target all the data cells in that column.

<col> is a void element (no children, no end tag) and is only valid inside a <colgroup> that does not itself carry a span attribute. Only a limited subset of CSS applies to columns: background, border (with border-collapse: collapse), visibility: collapse and width. Text and font properties do not inherit into the cells ? style those on <td> or <th> instead.

Since:

25.3
