Hello Bruno!
My modification was only working with tables having header cells .. here is
a bug fix to have it working for tables without header cells as well (again
in the PdfDocument.add(Element) method):
// new page
newPage();
// Bug fix start Gerald Fehringer: if something added through page
event
boolean somethingAdded = false;
if( currentHeight > 0 )
{
somethingAdded = true;
newLine();
flushLines();
indentTop = currentHeight - leading + 6;
currentHeight = 0;
}
else
{
flushLines();
}
// Bug fix end
// this part repeats the table headers (if any)
headercells = table.getHeaderCells();
int size = headercells.size();
if (size > 0) {
// this is the top of the headersection
cell = (PdfCell) headercells.get(0);
float oldTop = cell.top();
// loop over all the cells of the table header
for (int i = 0; i < size; i++) {
cell = (PdfCell) headercells.get(i);
// calculation of the new cellpositions
cell.setTop(indentTop()- oldTop + cell.top());
cell.setBottom(indentTop()- oldTop + cell.bottom() - 2f *
table.cellspacing());
pagetop = cell.bottom();
// we paint the borders of the cell
cellGraphics.rectangle(cell.rectangle(indentTop(),
indentBottom()));
// we write the text of the cell
ArrayList images = cell.getImages(indentTop(), indentBottom());
for (Iterator im = images.iterator(); im.hasNext(); ) {
cellsShown = true;
Image image = (Image) im.next();
addImage(graphics, image, 0, 0, 0, 0, 0, 0);
}
lines = cell.getLines(indentTop(), indentBottom());
float cellTop = cell.top(indentTop());
text.moveText(0, cellTop);
cellDisplacement = flushLines() - cellTop;
text.moveText(0, cellDisplacement);
}
currentHeight = indentTop() - pagetop - table.cellspacing();
text.moveText(0, pagetop - indentTop() + table.cellspacing() -
currentHeight);
}
// Bug fix start Gerald Fehringer: if no header cells and something
added through page event
else
{
if( somethingAdded )
{
pagetop = indentTop();
text.moveText(0, pagetop - indentTop() + table.cellspacing());
}
}
// Bug fix end
oldHeight = currentHeight;
Kind regards,
Gerald.
