Well, if I do not use -1 as for num of rows, I need split the data manually
so that they can fit to each pages. But there is another problem. It seems
that on 2nd and following pages, the table starts at the same location (same
Y value), but i want the table on the first page to be located at 1/3 of the
top, and on 2nd and other pages the table starts from the top of the page.
Part of my code is here:
int totalRows = 1000;
int numOfColumns = 5;
// read all the rows data
for (int i = 0; i < 1000; i++)
{
for (int j = 0; j < numOfColumns; j++)
{
PdfPCell num = new PdfPCell(new Paragraph("xxx " + i));
t.addCell(num);
}
}
// write first page of the table
// Note: The table starts at the 1/3 top of the page (Y = 300), and there
are 40 rows
table.setTotalWidth(document.right() - document.left());
table.writeSelectedRows(0, 40, document.left(), document.right(),
writer.getDirectContent());
// write the leftover of the rows to the tables on 2nd and more pages
// Note: the table on 2nd and following pages are starting at top of the
page (Y = 600).
int leftRows = 1000 - 40;
for (int i = 0; i < leftRows/80; i++) // 80 rows for each page
{
document.newPage();
table.setTotalWidth(document.right() - document.left());
table.writeSelectedRows(40 + i * 80, 100 + i * 80, document.left(),
document.right(), cb);
}
I have tried added these codes after write first page table rows, but this
does not move the table up to the top for 2nd pages and following ones:
PdfContentByte cb = writer.getDirectContent();
ColumnText ct = new ColumnText(cb);
float currentY = ct.getYLine();
currentY -= 200;
Is something wrong in my code? Howe can I make the table which holds
thousands of rows data have different Y values on different pages?
Here is the layout for better understanding:
page 1:
text
text, etc
table
page 2, 3, ....
table
last page:
table
text
Thanks
