POI中设置Excel单元格格式

POI中可能会用到一些需要设置EXCEL单元格格式的操作小结:

先获取工作薄对象:

HSSFWorkbook wb = new HSSFWorkbook();

HSSFSheet sheet = wb.createSheet();

HSSFCellStyle setBorder = wb.createCellStyle();

一、设置背景色:

setBorder.setFillForegroundColor((short) 13);// 设置背景色

setBorder.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

二、设置边框:

setBorder.setBorderBottom(HSSFCellStyle.BORDER_THIN); //下边框

setBorder.setBorderLeft(HSSFCellStyle.BORDER_THIN);//左边框

setBorder.setBorderTop(HSSFCellStyle.BORDER_THIN);//上边框

setBorder.setBorderRight(HSSFCellStyle.BORDER_THIN);//右边框

三、设置居中:

setBorder.setAlignment(HSSFCellStyle.ALIGN_CENTER); // 居中

四、设置字体:

HSSFFont font = wb.createFont();

font.setFontName("黑体");

font.setFontHeightInPoints((short) 16);//设置字体大小

HSSFFont font2 = wb.createFont();

font2.setFontName("仿宋_GB2312");

font2.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);//粗体显示

font2.setFontHeightInPoints((short) 12);

setBorder.setFont(font);//选择需要用到的字体格式

五、设置列宽:

sheet.setColumnWidth(0, 3766); //第一个参数代表列id(从0开始),第2个参数代表宽度值

六、设置自动换行:

setBorder.setWrapText(true);//设置自动换行

七、合并单元格:

Region region1 = new Region(0, (short) 0, 0, (short) 6);

//参数1:行号 参数2:起始列号 参数3:行号 参数4:终止列号

sheet.addMergedRegion(region1);

附一个完整的例子:

public static String outputFile = "c:\test.xls";

private void cteateCell(HSSFWorkbook wb, HSSFRow row, short col, String val) {

HSSFCell cell = row.createCell(col);

// cell.setEncoding(HSSFCell.ENCODING_UTF_16);

cell.setCellValue(val);

HSSFCellStyle cellstyle = wb.createCellStyle();

cellstyle.setAlignment(HSSFCellStyle.ALIGN_CENTER_SELECTION);

cell.setCellStyle(cellstyle);

}

public static void main(String argv[]) {

try {

// 创建新的Excel 工作簿

HSSFWorkbook workbook = new HSSFWorkbook();

// 设置字体

HSSFFont font = workbook.createFont();

// font.setColor(HSSFFont.COLOR_RED);

font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);

font.setFontHeightInPoints((short) 14);

// HSSFFont font2 = workbook.createFont();

// font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);

// font.setFontHeightInPoints((short)14);

// 设置样式

HSSFCellStyle cellStyle = workbook.createCellStyle();

cellStyle.setFont(font);

cellStyle.setAlignment(HSSFCellStyle.ALIGN_CENTER);

// HSSFCellStyle cellStyle2= workbook.createCellStyle();

// cellStyle.setFont(font2);

// cellStyle.setAlignment(HSSFCellStyle.ALIGN_CENTER);

// 在Excel工作簿中建一工作表,其名为缺省值

// 如要新建一名为"月报表"的工作表,其语句为:

11);

sheet.addMergedRegion(cellRangeAddress);

//第一行

// 在索引0的位置创建行(最顶端的行)

HSSFRow row = sheet.createRow(0);

// 在索引0的位置创建单元格(左上端)

HSSFCell cell = row.createCell(0);

// 定义单元格为字符串类型

cell.setCellType(HSSFCell.CELL_TYPE_STRING);

cell.setCellStyle(cellStyle);

// 在单元格中输入一些内容

cell.setCellValue(new HSSFRichTextString("北京亿卡联科技发展有限公司小区门禁维修月报表"));

//第二行
