FULL PRODUCT VERSION :
J2SE 6.0 beta 2
ADDITIONAL OS VERSION INFORMATION :
windows xp sp 2
mac ox 10.4.7
A DESCRIPTION OF THE PROBLEM :
When creating a table using <table width=100%>, and columns using a specified percentage width, the column size is calculated incorrectly, and teh columns widths are not the erquested percentage.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the supplied test case under both 1.4.2 and 1.5 or 1.6
resize the window, notice how under 1.4.2 the columns remain aligned (the table is 100% and the colums are 20% and 80%), under the later versions the column widths vary based on content. Actually, what I think is happeneding is that tha
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Each column should remain at its requested percentage width regardless of content.
REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
None.
I think the offending code is ColumnIterator.getMinimumSpan() in javax.swing.text.html.TableView
In 1.4.2, the method was:
public float getMinimumSpan(float parentSpan) {
if ((percentages != null) && (percentages[col] != 0)) {
return Math.max(percentages[col], columnRequirements[col].minimum);
}
return columnRequirements[col].minimum;
}
In 1.5 the method is
public float getMinimumSpan(float parentSpan) {
// do not care for percentages, since min span can't
// be less than columnRequirements[col].minimum,
// but can be less than percentage value.
return columnRequirements[col].minimum;
}
I made the changes in a local copy and it worked correctly.
