The JDK7 Spreadsheet demo has the broken display if user clicks on the cell outside of the numbers. As such, the table is no longer dislayed correctly


Test Configuration
------------------
    * OS: iMac 11.2 Mack OS X 10.7.2 - Intel Core i3
    * jdk build: jdk7-mac/ b222, b223
    * Spreadsheet demo applet

Steps to reproduce
------------------
0) Getting b223
1) Compiling /demos/applets/SpreadSheet/*.java
2) Invoke the SpreadSheet demo as
appletviewer /demos/applets/SpreadSheet/example1.html

3) Try to click on the cell which is outside of the numbers (example, the cell where letter A, B, C located)

If you see the broken display as the attached screesshot, the issue is reproducible
The issue has been a regression since b222 (worked fine in b221)
