poi导出word表格的操作讲解
时间：2020-09-30 13:00:30 | 栏目：JAVA代码 | 点击：次
一、效果如下
二、js代码
function export_word(){ //导出word
var url = "czzsca/exportWord.do";
this.export(url);
}
function export(url){
var currentyear = $("#mainYear").val() * 1;
var key_columns = ['xh',"d_name","d_unit","d_number","d_estimate","d_lastyear","jnjh","d_remarks","d_depart","d_executeunit"];
var value_columns = ['序号','项目名称','单位','数量','总概算','至'+(currentyear-1)+'年完成',currentyear+'年计划','附注','责任部门','计划执行单位'];
window.location.href= url+"?key_columns="+key_columns+"&value_columns="+value_columns+"&title="+currentyear+"年 更新改造计划 正式计划草案";
}
三、controller代码
（controller代码比较长，主要是格式化每一行的数据，主要是往工具类里传List<List<String>>参数，泛型的List<String>是每一行，String是每一列）
//导出word
@RequestMapping("/exportWord.do")
@ResponseBody
public ReturnMsg exportWord(String[] key_columns,String[] value_columns,String title,HttpServletResponse response){
ReturnMsg rm = new ReturnMsg();
try {
response.setCharacterEncoding("UTF-8");

五、详解：
1.设置纸张大小
（1）创建完XWPFDocument后，默认为A4纸张，如需调整纸张大小，这里我是要用A3大小使用如下代码
XWPFDocument doc= new XWPFDocument();
CTDocument1 document = doc.getDocument();
CTBody body = document.getBody();
if(!body.isSetSectPr()){
body.addNewSectPr();
}
CTSectPr section = body.getSectPr();
if(!section.isSetPgSz()){
section.addNewPgSz();
}
CTPageSz pageSize = section.getPgSz();
pageSize.setW(BigInteger.valueOf(15840));
pageSize.setH(BigInteger.valueOf(12240));
pageSize.setOrient(STPageOrientation.LANDSCAPE);
（2）默认A4纸张大小的话只用XWPFDocument
XWPFDocument doc= new XWPFDocument();
（3）使用CTPageSz类需要导入ooxml-schemas的jar包（所有需要的jar包maven依赖在底部）
2.单元格列宽度
（1）每一列宽度相等自适应，不需单独设置每一列宽度的话使用如下代码
//表格 XWPFTable ComTable = doc.createTable(); //表格自适应宽度 CTTblWidth comTableWidth = ComTable.getCTTbl().addNewTblPr().addNewTblW(); comTableWidth.setType(STTblWidth.DXA); comTableWidth.setW(BigInteger.valueOf(9072));
（2）单独设置每列宽度
//表格
XWPFTable ComTable = doc.createTable();
//设置指定宽度
CTTbl ttbl = ComTable.getCTTbl();
CTTblGrid tblGrid = ttbl.addNewTblGrid();
int[] colWidths = new int[] { 600, 3000, 500, 500, 800, 800 ,800,3000,800,1500};
for (int i : colWidths) {
CTTblGridCol gridCol = tblGrid.addNewGridCol();
gridCol.setW(new BigInteger(i+""));
}
（3）使用CTTblGrid类需要导入poi-ooxml-schemas的jar包（所有需要的jar包maven依赖在底部）
3.单元格内字体样式
（1）不需要设置单元格字体
for (int i = 0; i < rows; i++) {
XWPFTableRow rowsContent = ComTable.createRow();
for (int j = 0; j < list.get(i).size(); j++) {
rowsContent.getCell(j).setText(list.get(i).get(j)+""); //用单元格加载内容
}
}
（2）设置单元格内字体字号、是否加粗
for (int i = 0; i < rows; i++) {
XWPFTableRow rowsContent = ComTable.createRow();
for (int j = 0; j < list.get(i).size(); j++) {
XWPFParagraph cellParagraphC = rowsContent.getCell(j).getParagraphs().get(0);
if(j!=1&&j!=7) {
cellParagraphC.setAlignment(ParagraphAlignment.CENTER); //设置表格内容居中
}
XWPFRun cellParagraphRunC = cellParagraphC.createRun();
cellParagraphRunC.setFontSize(10); //设置表格内容字号
cellParagraphRun.setBold(true); //设置表头单元格加粗
cellParagraphRunC.setText(list.get(i).get(j)+""); //单元格段落加载内容
}
}
4.单元格居中（水平居中、垂直居中）
（1）使用单元格加载内容
for (int i = 0; i < value_columns.length; i++) {
XWPFTableCell cell = ComTable.getRow(0).getCell(i);
cell.setVerticalAlignment(XWPFTableCell.XWPFVertAlign.CENTER); //垂直居中
CTTc cttc = cell.getCTTc();
CTP ctp = cttc.getPList().get(0);
CTPPr ctppr = ctp.getPPr();
if (ctppr == null) {
ctppr = ctp.addNewPPr();
}
CTJc ctjc = ctppr.getJc();
if (ctjc == null) {
ctjc = ctppr.addNewJc();
}
ctjc.setVal(STJc.CENTER); //水平居中
}
（2）使用单元格的段落加载内容，只用调用垂直居中的方法
for (int i = 0; i < value_columns.length; i++) {
XWPFTableCell cell = ComTable.getRow(0).getCell(i);
cell.setVerticalAlignment(XWPFTableCell.XWPFVertAlign.CENTER); //垂直居中
}
水平居中在3-(2)里调用了段落的方法居中过了
cellParagraphC.setAlignment(ParagraphAlignment.CENTER);
5.单元格合并
（1）跨列合并单元格
public static void mergeCellsHorizontal(XWPFTable table, int row, int fromCell, int toCell) {
for (int cellIndex = fromCell; cellIndex <= toCell; cellIndex++) {
XWPFTableCell cell = table.getRow(row).getCell(cellIndex);
if ( cellIndex == fromCell ) {
cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.RESTART);
} else {
cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.CONTINUE);
}
}
}
（2）跨行合并单元格
public static void mergeCellsVertically(XWPFTable table, int col, int fromRow, int toRow) {
for (int rowIndex = fromRow; rowIndex <= toRow; rowIndex++) {
XWPFTableCell cell = table.getRow(rowIndex).getCell(col);
if ( rowIndex == fromRow ) {
cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.RESTART);
} else {
cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.CONTINUE);
}
}
}
6.单元格内换行，单元格内使用\r换行没用，可以用addBreak方法
for (int i = 0; i < list_vPostdutyNorm_parm.size(); i++) {
row = ComTable.createRow();
index++;
for (int j = 0; j < list_vPostdutyNorm_parm.get(i).size(); j++) {
if (j == 3 || j == 4) {
cellParagraph.setAlignment(ParagraphAlignment.LEFT); //设置表头单元格居中
} else {
cellParagraph.setAlignment(ParagraphAlignment.CENTER); //设置表头单元格居中
}
String content = list_vPostdutyNorm_parm.get(i).get(j);
cellParagraph = row.getCell(j).getParagraphs().get(0);
cellParagraphRun = cellParagraph.createRun();
cellParagraphRun.setFontSize(10); //设置表头单元格字号
cellParagraphRun.setBold(false); //设置表头单元格加粗
if (content.indexOf("\r") > -1) {
String[] text = content.split("\r");
for (int k = 0; k < text.length; k++) {
if (k == 0) {
cellParagraphRun.setText(text[k]);
}else {
cellParagraphRun.addBreak();
cellParagraphRun.setText(text[k]);
}
}
}else {
cellParagraphRun.setText(content);
}
}
}
六、使用到的Maven依赖
