poi导出word表格的操作讲解

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>参数，泛型的List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");

response.setContentType("application/msexcle");

response.setHeader("content-disposition", "attachment;filename="+new String("正式计划草案".getBytes("gb2312"),"ISO8859-1")+".doc");

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);

}
