Ireport defaults to automatically paging data to the next page when it exceeds the page length, but sometimes the business needs to customize the number of entries when it needs to display only a fixed number of lines on a page. Let's look at the specific operation.

1: add a variable to Variables first

2: edit the attribute. The expression of the variable is "new Integer (" 1 ")", and the evaluation type is "count" other default.

3: add a "Break" (page separator).

4: the page break modifies its property "print when expression" with the expression "new Boolean ($V {index} .intValue ()% 5values 0)".
