A DESCRIPTION OF THE REQUEST :
Can have 3D JTable with two or more RowHeaders and ColumnHeaders

JUSTIFICATION :
Its difficult to maintain selection, header size if we setHeaderView of a JScrollPane as another table

So JTable API can be refactored with a RowHeader

Also it will be better if we have a 3D JTable which will accept Vector of Vectors as JTable headers

So the final output will be a JTable with two or more row headers and two or more column headers

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
JTable with two or more row headers and two or more column headers
ACTUAL -
Currently the JTable supports only 2D data
