Text above pivot 我想在数据透视表中隐藏一列。如果我删除该列，则功能会生效。如何通过删除或隐藏数据透视表中的列来实现该功能？

我想在数据透视表中隐藏一列而不影响功能
答案 0 :(得分：0)
您可以使用setColumnHidden(int columnIndex, boolean hidden)隐藏一列，其中列A的columnIndex的值为0。 sheet.setColumnHidden(1, true)将隐藏B列。
隐藏列的另一种方法是使用setColumnWidth(int columnIndex, int width)，例如sheet.setColumnWidth(1, 0)也将执行与上述相同的操作。
我仍然会使用第一种专用于此目的的方法。
编辑-添加了以下说明，以说明其对数据透视表的有效性：
请注意，无论您是否具有正常的单元格或是否具有数据透视表（例如，在以下程序中，sheet.setColumnHidden(9, true)将隐藏列J（其列标签为 Average ）。
