前言
本文提供了一些利用Java設計Excel表格的參數，自定義設定需求表格，話不多說，直接上代碼
一、準備工作
這裡可以參考作者的上一篇文章，導入poi的包就可以。
自帶詳細注釋，小白也能看懂。
二、實作類源碼
1.
代碼如下（示例）：
//todo
//查詢資料
List<HospitalExcel> list = new ArrayList<>();
HospitalExcel hospitalExcel1 = new HospitalExcel();
HospitalExcel hospitalExcel2 = new HospitalExcel();
hospitalExcel1.setHospName("11111");
hospitalExcel1.setCCityName("兒童醫院");
hospitalExcel2.setHospName("1");
list.add(hospitalExcel1);
list.add(hospitalExcel2);
try {
//建立工作簿
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet("工作薄");//工作薄名稱
//設定每格資料的樣式
HSSFFont ParamFontStyle = workbook.createFont();
CellStyle cellParamStyle = workbook.createCellStyle();
cellParamStyle.setAlignment(HorizontalAlignment.CENTER);//垂直居中
cellParamStyle.setVerticalAlignment(VerticalAlignment.CENTER);//水準居中
cellParamStyle.setWrapText(false);//自動換行
ParamFontStyle.setFontHeightInPoints((short) 13);//字型大小
ParamFontStyle.setFontName("等線");
cellParamStyle.setFont(ParamFontStyle);
//設定表頭的樣式
HSSFFont ParamFontStyle1 = workbook.createFont();
CellStyle cellParamStyle1 = workbook.createCellStyle();
cellParamStyle1.setAlignment(HorizontalAlignment.LEFT);
cellParamStyle1.setVerticalAlignment(VerticalAlignment.DISTRIBUTED);
cellParamStyle1.setWrapText(false);//自動換行
ParamFontStyle1.setFontHeightInPoints((short) 15);
ParamFontStyle1.setFontName("黑體");
ParamFontStyle1.setBold(true);//是否打開加粗
cellParamStyle1.setFont(ParamFontStyle1);
//設定标題的樣式
HSSFFont ParamFontStyle2 = workbook.createFont();
CellStyle cellParamStyle2 = workbook.createCellStyle();
cellParamStyle2.setAlignment(HorizontalAlignment.CENTER);//垂直居中
cellParamStyle2.setVerticalAlignment(VerticalAlignment.CENTER);//水準居中
cellParamStyle2.setWrapText(true);//自動換行
ParamFontStyle2.setFontHeightInPoints((short) 14);
ParamFontStyle2.setFontName("黑體");
ParamFontStyle2.setBold(true);
cellParamStyle2.setFont(ParamFontStyle2);
//定義列的寬度
//sheet.setDefaultColumnWidth(40 * 1024);預設寬度
sheet.setColumnWidth(0,888);
sheet.setColumnWidth(1,5000);
sheet.setColumnWidth(2,5000);
sheet.setColumnWidth(3,5000);
sheet.setColumnWidth(4,5000);
sheet.setColumnWidth(5,5000);
sheet.setColumnWidth(6,5000);
sheet.setColumnWidth(7,5000);
sheet.setColumnWidth(8,5000);
sheet.setColumnWidth(9,5000);
sheet.setColumnWidth(10,5000);
//設定表頭
HSSFRow rows = sheet.createRow(0);
HSSFCell cell = rows.createCell(0);//一列的第一個單元格（下面的類似）
HSSFRow rows1 = sheet.createRow(1);
HSSFCell cell1 = rows1.createCell(0);
HSSFRow rows2 = sheet.createRow(2);
HSSFCell cell2 = rows2.createCell(0);
HSSFRow rows3 = sheet.createRow(3);
HSSFCell cell3 = rows3.createCell(0);
//合并單元格
CellRangeAddress region = new CellRangeAddress(0, 3, 5, 10);
sheet.addMergedRegion(region);
CellRangeAddress region1 = new CellRangeAddress(0, 0, 0, 4);
sheet.addMergedRegion(region1);
CellRangeAddress region2 = new CellRangeAddress(1, 1, 0, 4);
sheet.addMergedRegion(region2);
CellRangeAddress region3 = new CellRangeAddress(2, 2, 0, 4);
sheet.addMergedRegion(region3);
CellRangeAddress region4 = new CellRangeAddress(3, 3, 0, 4);
sheet.addMergedRegion(region4);
cell.setCellStyle(cellParamStyle1);
cell1.setCellStyle(cellParamStyle1);
cell2.setCellStyle(cellParamStyle1);
cell3.setCellStyle(cellParamStyle1);
cell.setCellValue("緻：" );
cell1.setCellValue("号碼：111111111111111111111");
cell2.setCellValue("金額：1111111111111111111");
cell3.setCellValue("日期：11111111111111111111");//填入值
//列名

//放入圖檔
