				<h1>TreeTable <span>Column Resize</span></h1>
				<p>Columns can be resized using drag drop by setting the resizableColumns to true. There are two resize modes; "fit" and "expand". Fit is the default one and the overall table width does not change when a column is resized.
                    In "expand" mode, table width also changes along with the column width.</p>
