Scrolling Of Rows Within A Table

This example looks like 1 table with rows that scroll similar to Excel's "freeze pane" feature.
Actually this example uses 2 tables.  The first table contains the headings and the other table contains the rows of data and it resides inside of a <div> tag which gives the scrolling look.
