Question

执行查询并进入一次所有数据。我不想在excel中显示表的某些列。我正在使用POI。现在最好给列名而不是列号来删除/跳过该列。在app.xml中，我指定了两个属性并尝试添加条件但没有获取如何添加。我的文件中有5张，我必须提到每张纸的属性标签。问题是我无法删除我在app.xml中提到的工作表中的列

<property key="sheet.name" value="abc"> <property key="column.name" value="chart,axis">

XSSFSheet sheet;
XSSFFont font = setFont(workBook.createFont(), bold, italic);
CellStyle cellStyle = workBook.createCellStyle();

        sheet.setDisplayGridlines(false);
        if (props.containsKey("sheet.name")) {
          sheetName = props.getProperty("sheet.name");
        }
        if (props.containsKey("colName.name")) {
          colName = props.getProperty("sheet.name");
          colName =  Arrays.asList( colName.split(","));
        }
        XSSFRow currentRow = sheet.createRow(rowNum);

        for (i = 0; i < headerData.size(); i++) {

将财产命名为：

<property key="skip.sheetname" value="column name(s) to delete" /> <property key="skip.sheetname" value="column name(s) to delete" />

然后试试这个：

if (props.containsKey("skip." + getSheetName())) {
     colName = props.getProperty("skip." + getSheetName());
     newList = Arrays.asList(colName.split(","));

     for (String skipHeader : newList) {
            Boolean flag = true;
            for (i = 0; i < headerData.size() && flag; i++) {
                if (headerData.get(i).equalsIgnoreCase(skipHeader)) {
                    headerData.set(i, "qwe");
                    flag = false;
                    skipColIndex.add(i);
                }

            }
    }
}

使用poi从excel跳过或删除列
