将excel表格（带图表）复制到另一个excel表格

我使用APACHE POI 3.0将表格添加到现有的Excel表格中。它工作正常。但是，由于APACHE POI在制作图表方面有局限性，我使用了一个模板excel文件来创建图表，这同样可以正常工作，但是这总会导致新的excel文件。如果我有一个现有的Excel工作表，并且我想添加一个工作表，并有图表，我无法做到这一点。因为，当我创建图表时，我使用模板文件，并且它总是生成一个新的excel文件。所以我想知道是否有添加片材到Excel，其中所述片材具有图表将excel表格（带图表）复制到另一个excel表格

以上是我的代码，它的一个代码。我分为两部分。部分是使用模板制作图表excel表单的部分。
