How to set column names

问题

I'm using Apache POI for my app and I want to set columns names instead of "A, B, C..."

I use the following code but it adds just data in first row:

 public void createHeaderRow(HSSFSheet sheet, List<String> headerRowList) {
    HSSFRow headerRow = sheet.createRow(0);
    for(int i=0;i<headerRowList.size();i++){
        HSSFCell cell = headerRow.createCell((short) i);
        cell.setCellValue(headerRowList.get(i).toString());
    }
}

So any ideas?

回答1:

Bad news: AFAIK excel cannot do anything different than A, B, C. The main reason: Column and Row names don't contain information, it's just a numbering. Imagine you want to print a document including these names: Excel won't know about formatting, nor borders, not even cell widths/heights.

You have the following options:

Use MS Access which uses database layout (eg Field names as Column names)
Fix the first row in the view and format it as table heading. Excel's table autoformat feature does it the same way.

For example :

JFileChooser save = new JFileChooser();
        save.setDialogTitle("Save file");
        int chooise = save.showSaveDialog(null);

        File file = null;
        if(chooise == JFileChooser.APPROVE_OPTION){
            file = save.getSelectedFile();
        }

        FileOutputStream fileOut;
        fileOut = new FileOutputStream(file.getAbsolutePath() + ".xls");
        HSSFWorkbook workbook = new HSSFWorkbook();
        HSSFSheet worksheet = workbook.createSheet("Workbook");
        Row row1 = worksheet.createRow((short)0);
        //Set columt names
        row1.createCell(0).setCellValue("Column Name 0");
        row1.createCell(1).setCellValue("Column Name 1");

etc.
