Apache Poi：Excel在'xxx.xlsx'中找到了不可读的内容 - 对于堆积条形图自定义颜色代码'，选择'是'后工作

Question

在这里，我创建了堆积条形图，代码正在运行，但它正在给出 - 'Excel在'xxx.xlsx'中找到了不可读的内容，这个错误在打开Excel文件时。

var ctShapeProperties = cTBarSer.addNewSpPr（）; ctShapeProperties.add Solid Fill（）。addNewSrgbClr（）。setVal（business）;

我已在堆积图表上为自定义颜色代码添加了此属性，同时删除此属性，在打开Excel时不会提示任何错误。

代码工作... ctShapeProperties - 即在cTBarSer.addNewIdx（）之后定义的形状属性.setVal（r - 1）;用于自定义颜色代码，而不是在打开Excel时提示错误。
