public static void exportExcel(HSSFWorkbook workbook,String sheetTitle, String[] headers,OutputStream out) {
/*
* 设置表头的样式
*/
// 生成一个表格
HSSFSheet sheet = workbook.createSheet();
workbook.setSheetName(0, sheetTitle);
// 设置表格默认列宽度为20个字节
sheet.setDefaultColumnWidth((short) 20);
// 生成一个样式
HSSFCellStyle style = workbook.createCellStyle();
// 设置这些样式
style.setAlignment(HorizontalAlignment.CENTER);
style.setVerticalAlignment(VerticalAlignment.CENTER);
//上下左右边框
style.setBorderBottom(BorderStyle.THIN);
style.setBorderTop(BorderStyle.THIN);
style.setBorderLeft(BorderStyle.THIN);
style.setBorderRight(BorderStyle.THIN);
// 生成一个字体
HSSFFont font = workbook.createFont();
font.setColor(IndexedColors.BLACK.index);
font.setFontHeightInPoints((short) 14);
font.setFontName("黑体");
// 把字体应用到当前的样式
style.setFont(font);
style.setFillPattern(FillPatternType.SOLID_FOREGROUND);
style.setFillForegroundColor(IndexedColors.GREY_25_PERCENT.index); //背景色
/*
* 设置标题样式
*/
HSSFCellStyle titleStyle = workbook.createCellStyle(); //标题样式
titleStyle.setAlignment(HorizontalAlignment.CENTER);

titleStyle.setBorderBottom(BorderStyle.THIN);
titleStyle.setBorderTop(BorderStyle.THIN);
titleStyle.setBorderLeft(BorderStyle.THIN);
titleStyle.setBorderRight(BorderStyle.THIN);
HSSFFont ztFont = workbook.createFont();
ztFont.setItalic(false); // 设置字体为斜体字
ztFont.setColor(IndexedColors.BLACK.index); // 将字体设置为“黑色”
ztFont.setFontHeightInPoints((short)18); // 将字体大小设置为18px
ztFont.setFontName("宋体"); // 将“宋体”字体应用到当前单元格上
ztFont.setBold(true); //加粗
titleStyle.setFont(ztFont);
// 在sheet里创建第一行，参数为行索引(excel的行)，可以是0～65535之间的任何一个
HSSFRow row2 = sheet.createRow(0);
row2.setHeightInPoints((short) 35);
// 创建单元格（excel的单元格，参数为列索引，可以是0～255之间的任何一个
HSSFCell cell2 = row2.createCell(0);
// 合并单元格CellRangeAddress构造参数依次表示起始行，截至行，起始列， 截至列
sheet.addMergedRegion(new CellRangeAddress(0, 0, 0, headers.length-1));
// 设置单元格内容
cell2.setCellValue("机电设备缺陷信息表");
cell2.setCellStyle(titleStyle);
// 产生表格标题行
HSSFRow row = sheet.createRow(1);
row.setHeightInPoints(23);//设置行高
sheet.setColumnWidth(0, 20*256);//设置列的宽度
for (int i = 0; i < headers.length; i++) {
HSSFCell cell = row.createCell((short) i);
cell.setCellStyle(style);
HSSFRichTextString text = new HSSFRichTextString(headers[i]);
cell.setCellValue(text.toString());
}
}
//下面代码是导出加上数据
// 遍历集合数据，产生数据行
//list对应的是类型List<List<String>> 此处这个list已经是所有的数据，一行数据是List<String>
if (list != null) {
int index = 2;//从第一几行开始
for (List<String> m : list) {
row = sheet.createRow(index);
int cellIndex = 0;
for (String str : m) {
HSSFCell cell = row.createCell((short) cellIndex);
if (str == null) {
str = "";
}
cell.setCellValue(str.toString());
cellIndex++;
}
index++;
}
}
