Use the HtmlTable.Height property to control the height of the System.Web.UI.HtmlControls.HtmlTable control. The height is normally specified in pixels. However, you can also specify a percentage of the browser window height by appending a percent sign (%) to the value. For example, the value 100% indicates a height for the table that is the full height of the browser window. The table automatically expands and contracts as the user changes the window size.
