Perhaps I don't understand the use of PdfPTableEvent well enough. If my
table spans multiple pages, how can I use the information in the
PdfPTableEvent to determine the appropriate borders? Can I use the canvas
to write across previous pages? If so, then perhaps this would be better,
although the changes to allow PdfPTable to have a border also seem fairly
simple. Here is what I did to evaluate this:
In PdfPTable.writeSelectedRows(int colStart, int colEnd, int rowStart, int
rowEnd, float xPos, float yPos, PdfContentByte[] canvases), I added the
following at the very end:
setLeft(xPos);
setRight(xPos + getTotalWidth());
setTop(yPosStart);
setBottom(yPos);
Rectangle borderRect = new Rectangle(this);
if (hasPreviousSubtables) {
borderRect.disableBorderSide(Rectangle.TOP);
}
if (hasMoreSubtables) {
borderRect.disableBorderSide(Rectangle.BOTTOM);
}
canvases[LINECANVAS].rectangle(borderRect);
Note the new members hasPreviousSubtables and hasMoreSubtables (names
debateable). Other small changes to make sure new Rectangle properties are
copied appropriately.
In ColumnText (starting at line 1279 of my version) I added:
if (listIdx > 0) {
nt.hasPreviousSubtables = true;
}
if (k < table.size()) {
nt.hasMoreSubtables = true;
}
this is right before the line:
nt.writeSelectedRows(0, -1, x1, yLineWrite, canvas);
This seems fairly straightforward, but I don't quite follow all of the
ColumnText code, so I may be missing something important.
If this is something you would like to pursue, then I need to make some
small changes to accomodate the variable width border code I am using. I
can do that and send you the two updated files.
