(This is in the context of setting the width on XWPFTable.)
I decided that the best (and simplest) approach would be to use strings to set
the width value for "auto" and percentages, rather than creating a separate
class that would just end up creating a percentage string anyway. This also
matches the way the API is likely to be used, e.g., getting percentage value
strings from some incoming source.
So I added a new setWidth(String widthValue) method to XWPFTable() which
validates that it's a good value ("auto", an integer, or a percentage) and then
if it's good, sets the value appropriately.
I also created a new method, getWidthDecimal(), to return the width value as a
decimal (because percentages can be decimal values).
Using this test case:
XWPFDocument doc = new XWPFDocument();
XWPFTable xtab = doc.createTable();
assertEquals(0, xtab.getWidth());
assertEquals(STTblWidth.AUTO, xtab.getWidthType());
xtab.setWidth(1000);
assertEquals(STTblWidth.DXA, xtab.getWidthType());
assertEquals(1000, xtab.getWidth());
xtab.setWidth("auto");
assertEquals(STTblWidth.AUTO, xtab.getWidthType());
assertEquals(0, xtab.getWidth());
assertEquals(0.0, xtab.getWidthDecimal(), 0.01);
xtab.setWidth("999");
assertEquals(STTblWidth.DXA, xtab.getWidthType());
assertEquals(999, xtab.getWidth());
xtab.setWidth("50.5%");
assertEquals(STTblWidth.PCT, xtab.getWidthType());
assertEquals(50.5, xtab.getWidthDecimal(), 0.01);
assertEquals(50.5,
xtab.getCTTbl().getTblPr().getTblW().xgetW().getBigDecimalValue().doubleValue(),
0.01);
Everything passes until the last test, where the value returned by
getWidthDecimal() is 50.0, not 50.5.
It looks like the underlying CT class methods always set the value as an
integer, even when using CTTblWidth.setBigDecimalValue():
} else if (widthValue.matches("[0-9]+(\\.[0-9]+)?%")) {
String numericPart = widthValue.substring(0, widthValue.length() -
1);
STDecimalNumber number = STDecimalNumber.Factory.newInstance();
number.setBigDecimalValue(new BigDecimal(numericPart));
ctWidth.xsetW(number);
ctWidth.setType(STTblWidth.PCT);
Debugging through this code I see that the @w:val attribute is "50" rather than
"50.5" after the xsetW() method call.
This appears to be happening at a very low level.
Is there a way to fix this so that percentages can be decimals or have I
misunderstood the specs and percentages should actually always be integers
(although I'm pretty sure the spec allows fractional percentages).
Thanks,
Eliot

I need to extend the options for setting table widths.
Per the spec, a table's width can be an absolute measurement, a percentage
value, or the keyword "auto".
Right now XWPFTable.setWidth() only takes an integer.
I'd like to extend it to take in addition a percentage value or the value
"auto" (which I suppose conceptually is an enumeration with one possible value).
There doesn't seem to be a class that represents a percentage value (at
least I couldn't find any declarations with the string "perc" in them.
Am I missing something for working with percentage values in the XWPF API?
Thanks,
E.
