本文介绍了一种在报表中实现精确分页的方法，通过创建一个包含特定数量记录的组，并利用表达式设置页面断点，使得报表能够按照预设的行数进行分页。
报表可以通过设置其Layout的大小来控制分页，但是如何更精确的按照每N行记录对报表分页？

Page Breaks
In some reports, you may want to place a page break at the end of a specified number of rows instead of, or in addition to, on groups or report items. To do this, create a group in a data region (typically a group immediately outside the detail), add a page break to the group, and then add a group expression to group by a specified number of rows.
* The following expression, when placed in the group expression, assigns a number to each set of 25 rows. When a page break is defined for the group, this expression results in a page break every 25 rows.
=Int((RowNumber(Nothing)-1)/25)
