col.md

col - DOM interface API

The col element

Current

HTMLTableColElement, same as for colgroup elements. This interface defines one member, span.

Table Usability

interface HTMLTableVectorElement : HTMLElement {
    readonly attribute HTMLCollection cells;
    readonly attribute HTMLCollection headers;
    readonly attribute HTMLCollection headersGroup;
    readonly attribute long level;
    readonly attribute long index;
    readonly attribute long groupIndex;
    readonly attribute DOMString scope;
};

interface HTMLTableColElement : HTMLTableVectorElement {
    readonly attribute long start;
    readonly attribute long end;
}

Idea behind

Provide the same segmentic of a tr element but in the colum scope.

Table Parser - WET 3.0 release

jQuery.data tblparser  {
    array cell;
    jQuery elem;
    long end;
    groupZero {
        // Reference to the structure attached to the table element
    };
    groupstruct {
        // Reference to the structure attached to the associated colgroup element
    };
    array header;
    long start;
    long type;
    long uid;
}
