修复的记录：/xl/tables/table1.xml 部分的表（表）

Question

我正在寻找使用 apache poi 在 excel 表最后显示总计行的代码。

为了简化问题，我实现了示例代码，在 Excel 工作表中生成一个包含一些虚拟数据的表格。

代码正在运行，但是当我打开生成的 Excel 工作簿时，我收到如下所示的警告消息。

代码有问题吗？

欢迎来到 Microsoft Office Open XML 的勇敢世界。对于桌子来说，两者总是需要的。一旦设置在表 XML 中，然后设置在相应的工作表中。

就总计行而言，即第一个表格列的总计行标签和工作表中相应的字符串单元格值以及表格列的总计行函数和工作表中的相应公式。

...
        // add totals row to table
        
        Row totalsRow = sheet.createRow(11);
        // set totals row label for table column 0
        table.getCTTable().getTableColumns().getTableColumnList().get(0).setTotalsRowLabel("Totals");
        // set sheet cell value for this            
        totalsRow.createCell(0).setCellValue("Totals");;

        table.getCTTable().setTotalsRowShown(true);
        table.getCTTable().setTotalsRowCount(1);

        // set totals row function for table column
        table.getCTTable().getTableColumns().getTableColumnList().get(1).setTotalsRowFunction(
            org.openxmlformats.schemas.spreadsheetml.x2006.main.STTotalsRowFunction.SUM);   
        // set sheet cell formula for this          
        totalsRow.createCell(1).setCellFormula(String.format("SUBTOTAL(109,%s[%s])",tableName,  "Header 2"));
            
        // set totals row function for table column
        table.getCTTable().getTableColumns().getTableColumnList().get(2).setTotalsRowFunction(
            org.openxmlformats.schemas.spreadsheetml.x2006.main.STTotalsRowFunction.SUM);   
        // set sheet cell formula for this          
        totalsRow.createCell(2).setCellFormula(String.format("SUBTOTAL(109,%s[%s])",tableName,  "Header 3"));
