Apache poi - 打印布局，在同一张纸上有多个打印区域 [英] Apache poi - print layout, more than one print area in the same sheet

问题描述

我正在尝试开发一个复杂的报告，我需要为 excel 文件设置打印区域.我必须将 xls 文件分成 3 部分，但是如果我执行 setPrintArea(..) 新区域订阅旧区域，结果是我在打印预览中只有最后一页.如何设置多个打印区域?这是代码:

I'm trying to develop a complex report, and I need to set up the print areas for the excel file. I must divide the xls file in 3 part, but if I do setPrintArea(..) the new area subscribe the old and the result is that I have in the print preview only the last page. How can I set more than one print area? This is the code:

protected void createCustomerSheet(String label) {
    createSheet(label);
    getCurrentSheet().getPrintSetup().setPaperSize(PrintSetup.A4_PAPERSIZE);
    getCurrentSheet().getPrintSetup().setFitHeight((short)1);
    getCurrentSheet().getPrintSetup().setFitWidth((short)1);
    getCurrentSheet().setAutobreaks(true);
    getCurrentSheet().setFitToPage(true);
}

然后我打了3次电话

 wb.setPrintArea(activeSheetIndex, startColumn, endColumn, startRow, endRow);

我也尝试添加中断行，但它不起作用..

I also tried to add break rows, but it doesn't work..

有什么想法吗?

推荐答案

Excel 只维护一个 打印区域 用于电子表格.所以Apache POI的Excel API提供了设置一个打印区域的能力.

Excel maintains only one print area for a spreadsheet. So Apache POI's Excel API provides the ability to set one print area.

听起来您可能正在尝试定义报告的不同页面.如果是这样，您需要在要完成此操作的每个工作表中设置行和/或列分隔符.使用Sheet的以下方法，假设sheet 是你的 Sheet 实例:

It sounds like you might be trying to define different pages of a report. If so, you'll need to set row and/or column breaks in each Sheet in which you want this done. Use the following methods of Sheet, assuming sheet is your Sheet instance:

sheet.setAutobreaks(false);
sheet.setRowBreak(rowIndex);
sheet.setColumnBreak(columnIndex);

您可以多次调用最后两个方法中的每一个以建立多个中断.

You may call each of those last 2 methods multiple times to establish multiple breaks.
