Hi,
I have a situation where a PDFPTable is created iterating on a Java
object containing all data and then it is added to the document object.
Now, I have to make a page break(or create a new page) when a
condition is met while creating the PDFPTable.
If I do document.newPage(), it makes no effect. What am I missing or
what do I need to add ?
First you need to know that document.newPage() only adds a new page if
the current page isn't blank.
Now let's look at your logic.
You create a table with 1 column => nothing is added to the document.
You add a cell to the table => the table grows, nothing is added to the
document.
You add a cell to the table => the table grows, nothing is added to the
document.
You add a cell to the table => the table grows, nothing is added to the
document.
You invoke document.newPage() => iText creates a new page, unless the
current page is blank
You add a cell to the table => the table grows, nothing is added to the
document.
You add a cell to the table => the table grows, nothing is added to the
document.
You add a cell to the table => the table grows, nothing is added to the
document.
You invoke document.newPage() => iText doesn't add a new page, because
nothing was added to the document since the previous newPage
You add a cell to the table => the table grows, nothing is added to the
document.
You add a cell to the table => the table grows, nothing is added to the
document.
You add a cell to the table => the table grows, nothing is added to the
document.
You add the table to the document => A table with nine rows is added to
the document.
It should be obvious that row 4 and 7 don't start on a new page.
You've built the table in memory. As long as you don't add the table to
the document, the document isn't aware that you're building a table. The
table isn't aware of the fact that you wanted row 4 and 7 to start on a
new page.
As you should now understand, this is not an iText problem; this is a
case of elementary logic.
