我正在开发Android版生成 PDF的应用程序。

I am developing an app for android that generates pdf.

我使用 itextpdf 生成PDF。

我有以下问题：

我有一个具有3行和当该表是靠近页的结束，有时它把一个行上的一个页面和下页面上两行的表。

I have a table that has 3 rows and when this table is near the end of a page sometimes it puts one row on one page and two rows on the next page.

有没有办法来强制此表，开始下一个页面上，所以我可以有充分的下页表格？

Is there a way to force this table to start on the next page so I can have the full table on the next page?

感谢

推荐答案

请看看在分割例如：

Paragraph p = new Paragraph("Test");
PdfPTable table = new PdfPTable(2);
for (int i = 1; i < 6; i++) {
    table.addCell("key " + i);
    table.addCell("value " + i);
}
for (int i = 0; i < 40; i++) {
    document.add(p);
}
document.add(table);

我们有5行的表，并且在这种情况下，我们增加一些段落使得表被添加在页面的末尾。

We have a table with 5 rows, and in this case, we're adding some paragraphs so that the table is added at the end of a page.

在默认情况下，iText的会尽量不拆行，但如果全表不适合，它会转发不适合到下一页的行：

By default, iText will try not to split rows, but if the full table doesn't fit, it will forward the rows that don't fit to the next page:

您想避免这种行为：你不想表分割

You want to avoid this behavior: you don't want the table to split.

因为知道iText的将尽量保持全行不变，则可以解决这个问题，通过嵌套表你不想要分割另一个表内：

Knowing that iText will try to keep full rows intact, you can work around this problem by nesting the table you don' want to split inside another table:

PdfPTable nesting = new PdfPTable(1);
PdfPCell cell = new PdfPCell(table);
cell.setBorder(PdfPCell.NO_BORDER);
nesting.addCell(cell);
document.add(nesting);

现在你会得到这样的结果：

Now you get this result:

目前是previous页上有足够的空间来呈现一对夫妇行，但我们已经裹满表中的行内有一列，iText的将转发完整的表到下一个页面。

There was sufficient space on the previous page to render a couple of rows, but as we've wrapped the full table inside a row with a single column, iText will forward the complete table to the next page.
