问题描述

我使用Apache POI，我需要把边框的单元格区域或合并区域。我合并将细胞与三行和五列。但我不能够边框添加到它。所以，我该怎么做呢？

I'm using Apache POI and I need to put a border in a range of cells or merged region. I am merging the cells with three rows and five columns. But I am not able to add the border to it. So how do I do this?

推荐答案

我的解决办法是通过自己的立场，以合并的单元格，然后创建一个单元格（参考合并单元格的第一个块）分配一个值，然后设置边境throught的<一个href=\"http://poi.apache.org/apidocs/org/apache/poi/ss/util/class-use/CellRangeAddress.html\">HSSFRegionUtil

My solution was to merge the cells by their positions, then created a cell (reference to the first block of the merged cells) to assign a value and then set the border throught the HSSFRegionUtil

// Merges the cells
CellRangeAddress cellRangeAddress = new CellRangeAddress(start, start, j, j + 1);
sheet.addMergedRegion(cellRangeAddress);

// Creates the cell
Cell cell = CellUtil.createCell(row, j, entry.getKey());

// Sets the borders to the merged cell
HSSFRegionUtil.setBorderTop(CellStyle.BORDER_MEDIUM, cellRangeAddress, sheet, workbook);
HSSFRegionUtil.setBorderLeft(CellStyle.BORDER_MEDIUM, cellRangeAddress, sheet, workbook);
HSSFRegionUtil.setBorderRight(CellStyle.BORDER_MEDIUM, cellRangeAddress, sheet, workbook);
HSSFRegionUtil.setBorderBottom(CellStyle.BORDER_THIN, cellRangeAddress, sheet, workbook);
