自动宽度不适用于合并的列

问题描述

{
row=sheet.createRow(0);
cell=row.createCell(0);
cell.setCellValue("header");
cell=row.createCell(1);
sheet.addMergedRegion(new CellRangeAddress(0,0,0,1));
row=sheet.createRow(1);
cell=row.createCell(0);
cell.setCellValue("Keys");
cell=row.createCell(1);
cell=row.setCellValue("Values");
row=sheet.createRow(2);
cell=row.createCell(0);
cell.setCellValue("No data");
cell=row.createCell(1);
sheet.addMergedRegion(new CellRangeAddress(1,1,0,1);
sheet.autoSizeColumn(0);
}

当我合并零行的两列时，自动大小有效，但是在合并第二行的两列后，自动大小不起作用.预先感谢...

autosize is working when I merged two columns of row zero, but after merging two columns of second row autosize is not working..thanks in advance...

推荐答案

我发现了您的问题，它是这一行:

I've spotted your problem, it's this line:

sheet.autoSizeColumn(0);

来自 javadocs上autoSizeColumn(int)我们看到以下关键信息:

From the javadocs on autoSizeColumn(int) we see this key bit of information:

您需要切换到 autoSizeColumn(int，boolean)，然后传入一个真值.这将告诉POI在调整大小时要考虑合并的像元.因此，您的代码应改为:

You need to switch to instead call autoSizeColumn(int,boolean), and pass in a true value. This will tell POI to take account of merged cells during the sizing. So, your code should instead be:

sheet.autoSizeColumn(0, true);
