	 * Constructor for a new Table.

	 * @param {object} [mSettings] Initial settings for the new control
	 *
	 * @class
	 * The <code>sap.m.Table</code> control provides a set of sophisticated and convenience functions for responsive table design.
	 *
	 * To render the <code>sap.m.Table</code> control properly, the order of the <code>columns</code> aggregation should match with the order of the <code>cells</code> aggregation (<code>sap.m.ColumnListItem</code>).
	 *
	 * The <code>sap.m.Table</code> control requires at least one visible <code>sap.m.Column</code> in the <code>columns</code> aggregation, therefore applications must avoid configuring all columns to be shown in the pop-in.
	 * If such a conflict is detected, then the table prevents one column from moving to the pop-in.
	 *
	 * For mobile devices, the recommended limit of table rows is 100 (based on 4 columns) to assure proper performance. To improve initial rendering of large tables, use the <code>growing</code> feature.
	 *
	 * See section "{@link topic:5eb6f63e0cc547d0bdc934d3652fdc9b Creating Tables}" and "{@link topic:38855e06486f4910bfa6f4485f7c2bac Configuring Responsive Behavior of a Table}"

				/**
				 * Defines the algorithm to be used to layout the table cells, rows, and columns.
				 * This property allows three possible values:
				 * <ul>
				 * <li><code>true</code></li>
				 * <li><code>false</code></li>
				 * <li><code>Strict</code></li>
				 * </ul>
				 *
				 * By default, the table is rendered with a fixed layout algorithm (<code>fixedLayout=true</code>). This means the horizontal layout only depends on the table's width and the width of the columns, not the content of the cells. Cells in subsequent rows do not affect column width. This allows a browser to provide a faster table layout since the browser can begin to display the table once the first row has been analyzed.
				 *
				 * If this property is set to <code>false</code>, <code>sap.m.Table</code> is rendered with an auto layout algorithm. This means, the width of the table and its cells depends on the content of the cells. The column width is set by the widest unbreakable content inside the cells. This can make the rendering slow, since the browser needs to go through all the content in the table before determining the final layout.<br>
				 *
				 * If this property is set to <code>Strict</code> and the <code>width</code> property is defined for all columns (and not the expected "auto" value), then the <code>sap.m.Table</code> control renders a placeholder column which occupies the remaining width of the control to ensure the column width setting is strictly applied.<br>
				 *
				 * If there is only one remaining column with a width larger than the table, then this column gets the maximum width available in the table. If the column width is smaller than the table, then the column width is retained, and the remaining width of the table is occupied by the placeholder column.<br>
				 *
				 * The placeholder column gets rendered only if there are no columns in the pop-in area.<br>
				 *
				 * <b>Note:</b> Since <code>sap.m.Table</code> does not have its own scrollbars, setting <code>fixedLayout</code> to false can force the table to overflow, which may cause visual problems. It is suggested to use this property when a table has a few columns in wide screens or within the horizontal scroll container (e.g <code>sap.m.Dialog</code>) to handle overflow.
				 * In auto layout mode the <code>width</code> property of <code>sap.m.Column</code> is taken into account as a minimum width.

				 *
				 * For example, by setting the <code>contextualWidth</code> property to 600px or Tablet, the table can be placed in a container with 600px width, where the pop-in is used.
				 * You can use specific CSS sizes (for example, 600px or 600), you can also use the <code>sap.m.ScreenSize</code> enumeration (for example, Phone, Tablet, Desktop, Small, Medium, Large, ....).
				 * If this property is set to <code>Auto</code>, the <code>ResizeHandler</code> will manage the contextual width of the table.
				 * <b>Note:</b> Only "Inherit", "Auto", and pixel-based CSS sizes (for example, 200, 200px) can be applied to the <code>contextualWidth</code> property. Due to the rendering cost, we recommend to use the valid value mentioned before except for "Auto".
