org.apache.juneau.bean.html5.Col

@Marshalled(typeName="col")
public class Col
extends HtmlElementVoid<Col>

DTO for an HTML <col> element.

The col element represents one or more columns in a column group represented by its parent colgroup element. It is used to define the structural columns of a table and can specify attributes that apply to all cells in those columns. The col element is a void element that does not contain any content and is typically used within a colgroup element to define column properties such as width, alignment, and styling.

Examples:

import static org.apache.juneau.bean.html5.HtmlBuilder.*; // Simple column Col simple = col(); // Column spanning multiple columns Col spanning = col().span(3); // Column with styling Col styled = col() .class_("highlight-column") .style("background-color: #f0f0f0;"); // Column with width Col withWidth = col() .style("width: 200px;"); // Column with alignment Col aligned = col() .style("text-align: center;"); // Column with ID Col withId = col() .id("name-column") .span(2); // Column with multiple attributes Col complex = col() .span(2) .class_("data-column") .style("width: 150px; text-align: right;") .title("Numeric data column");
