poi设置word表格单元格宽度_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");

List> content = new ArrayList>();

List> head = new ArrayList>();

String jnjhzh = new BigDecimal(this.map.get("jnjhzh")==null||"".equals(this.map.get("jnjhzh")+"")?"0":this.map.get("jnjhzh")+"").setScale(1, RoundingMode.UP)+"";

String trimpro = new BigDecimal(this.map.get("tzjh")==null||"".equals(this.map.get("tzjh")+"")?"0":this.map.get("tzjh")+"").setScale(1, RoundingMode.UP)+"";

String temp = new BigDecimal(trimpro).subtract(new BigDecimal(jnjhzh))+"";

if("0".equals(temp)) {

temp = "";

}

head = ExportUtil.getCzzscaList(jnjhzh, trimpro, temp);

Map dounit = new HashMap();

dounit.put("dwlx", 0);

dounit.put("user_type", 1);

List d_executeunit = unitDao.selectByPrimaryKey(dounit);

Map zrbm = new HashMap();

zrbm.put("dwlx", 1);

zrbm.put("user_type", 1);

List d_zrbm = unitDao.selectByPrimaryKey(zrbm);

List zmtype = nd_caController.findProType("2-3-4");

for (Map map: this.list) {

List row = new ArrayList();

for (int i = 0; i < key_columns.length; i++) {

System.out.print(map.get(key_columns[i])+",");

Object Otzjh = map.get("tzjh")!=null?map.get("tzjh"):0;

Object Ojnjh = map.get("jnjh")!=null?map.get("jnjh"):0;

BigDecimal tzjh = null;

BigDecimal jnjh = null;

if ("tzjh".equals(key_columns[i])||"jnjh".equals(key_columns[i])||"d_lnorde".equals(key_columns[i])) {

if(Otzjh instanceof BigDecimal) {

tzjh = (BigDecimal)Otzjh;

}else {

tzjh = new BigDecimal(Otzjh+"");

}

if(Ojnjh instanceof BigDecimal) {

jnjh = (BigDecimal)Ojnjh;

}else {

jnjh = new BigDecimal(Ojnjh+"");

}

}

if ("d_lnorde".equals(key_columns[i])) {

if(map.get("flag")!=null&&"2".equals((map.get("flag")+""))) {

row.add("");

}else {

row.add(tzjh.subtract(jnjh).setScale(1, RoundingMode.UP)+""); //不为整数则四舍五入

}

}else if ("xh".equals(key_columns[i])&&map.get("xh")!=nu
