public class ERXTable
extends WOTable

Enhanced table component that adds the ability to have the table layed out in a vertical orientation and adds the ability to specify an array of header images that appear in the header cells of the table. Corrects a bug intorduced in WO 5.1 where OutOfBounds exceptions are thrown. Note that this component subclasses WOTable from this framework, not the WOTable in com.webobjects.woextensions. The reason for this is that all of the instance variables are private in JavaWOExtensions WOTable.

Synopsis:
list=anArray;item=aSettableObject;[col=aSettableNumber;][index=aSettableNumber;][row=aSettableNumber;] [maxColumns=aNumber;][tableBackgroundColor=aString;][border=aNumber;][cellpadding=aNumber;][cellspacing=aNumber;] [rowBackgroundColor=aString;][cellBackgroundColor=aString;][cellAlign=aNumber;][cellVAlign=aNumber;] [cellWidth=aNumber;][tableWidth=aNumber;] [goingVertically=aBoolean;][headerImages=anArray;][headerRowBackgroundColor=aColor;]
