A table column. 
<p>
A WTableColumn is returned by <a class="el" href="classWt_1_1WTable.html#37dc3995a309d32a0e4bf857596df00e" title="Returns the column object for the given column.">WTable::columnAt()</a> and managing various properties of a single column in a table (it is however not a widget).<p>
You cannot access table cells through the column. Instead, to access table cells, see <a class="el" href="classWt_1_1WTable.html#c4b59af9a44e185edb14e7f1f439d6c4" title="Accesses the table element at the given row and column.">WTable::elementAt()</a>.<p>
A table column corresponds to the HTML <code>&lt;col&gt;</code> tag.<p>

For a WWidget, this corresponds to the id of the DOM element that represents the widget. This is not entirely unique, since a <a class="el" href="classWt_1_1WCompositeWidget.html">composite widget</a> shares the same id as its implementation.<p>
By default, the id is auto-generated, unless a custom id is set for a widget using <a class="el" href="classWt_1_1WWidget.html#93ff9d1ca04e733cd54cd40a06775f7e" title="Sets the CSS Id.">WWidget::setId()</a>. The auto-generated id is created by concatenating <a class="el" href="classWt_1_1WObject.html#5cad0cc3f73402de1422747653ece18f" title="Returns the object name.">objectName()</a> with a unique number.<p>
