如何格式化 POI 创建的 Excel 文档

Question

我正在使用 POI 创建 Excel 文档的应用程序。问题是，在没有任何数据的情况下生成 Excel 很好，但是当我将数据与它一起放置时，headers 正在下降。我的代码：

            HSSFWorkbook hwb = null;
            hwb = new HSSFWorkbook();
            HSSFSheet sheet = hwb.createSheet("new sheet");

            HSSFRow rowhead = sheet.createRow((short) largest);

            HSSFCell intervieweeName = rowhead.createCell(0);
            intervieweeName.setCellValue("Interviee Name");

            HSSFCell interviewTiming = rowhead.createCell(1);
            interviewTiming.setCellValue("Interview Timing");

    for (int large = 0; large < largest; large++) {

            int i=0;
            HSSFRow array1 = sheet.createRow((short)large);
            for ( i = i + large; i < interviewerNameList.size(); i++) { 
            HSSFCell tracker1 = array1.createCell(0);
            HSSFCell tracker2 = array1.createCell(1);

            tracker1.setCellValue(interviewerNameList.get(large));
            tracker2.setCellValue(interviewTimingToFrom1.get(large));

            }
            }

问题是标题 Interviee Name 和 Interview Timing 出现在值之后。

Answer 1

您的问题是您将 header 写入最后一行

HSSFRow rowhead = sheet.createRow((short) largest);
...
for (int large = 0; large < largest; large++) {
    HSSFRow array1 = sheet.createRow((short)large);

将 header 放在末尾，并从 0 循环到它以创建数据行

将其改为：

HSSFRow rowhead = sheet.createRow(0);
...
for (int large = 0; large < largest; large++) {
    HSSFRow array1 = sheet.createRow(large+1);

这样，large 变量在您的数据查找中保持不变，但您从第 1 行开始填充内容
