Blank page if second PTable is not fit on 1 page.

[chaco89]

I created 2 PTable, both table should be in separated page. Step 1. document.add(table1) -> fits on page Step 2. document.newPage() Step 3. document.add(table2) -> this is not fit on 1 page, It's dynamic table. The blank page is occurs on page 2. Page 1 -> table 1 (fits) Page 2 -> blank Page 3 -> table 2 Page 4 -> table 2 (continued).

The method addPTable, in looping create a newPage in the first loop.

while (true) {
            ct.setSimpleColumn(indentLeft(), indentBottom(), indentRight(), indentTop() - currentHeight);
            int status = ct.go();
            if ((status & ColumnText.NO_MORE_TEXT) != 0) {
                text.moveText(0, ct.getYLine() - indentTop() + currentHeight);
                currentHeight = indentTop() - ct.getYLine();
                break;
            }
            if (indentTop() - currentHeight == ct.getYLine())
                ++loop;
            else
                loop = 0;
            if (loop == 3) {
                add(new Paragraph("ERROR: Infinite table loop"));
                break;
            }
            newPage();
        }

This probably correct if i didn't call newPage(), but if i didn't call a newPage() and table 2 fits on 1 page, Both table is not in separated page. Please give me a suggestion. Should this code changed when the first time loop won't create a new page ?

You code is hard to understand, because there are missing some information about the variables and methods you are using and how you build your table (for example. what is newPage() doing?). That's why I can't reproduce your problem.

I've made a short example and with this it worked. The first table is on the first page. Then the second table is on the second page and continues on the third page.

Maybe this helps you.

Agree with @razilein, his provided code works and couldn't see any blank page [Verified on openPdf-1.3.29]
