我正在使用动态报告创建报告。有我的代码。当我运行它给出错误。我的内容这么大（详细）。请帮我解决这个问题。当我的内容（详细信息）为 10 行时，此代码运行良好。但是当我的内容（详细信息）很大时，它会出错。
错误：
net.sf.dynamicreports.report.exception.DRException: net.sf.jasperreports.engine.design.JRValidationException: Report design not valid :
1. The detail section, the page and column headers and footers and the margins do not fit the page height.
