概述
网上java导出excel表格并合并单元格的资料不完全，我整理了一份，并亲测能用，附截图。
①java导出excel用到POI所有jar包，大家可以直接到下面地址下载点击打开链接
②模拟数据类
package org;
public class WorkSheetDetail {
//工作内容
private String workCtx;
// 用工人总数 工日数 = gwnNum+tmnNum
private Float totalHumanDays;
//普工用工数 1-4小时为半天，4-8小时为一天;120每天
private Integer gwnNum;
//技工用工数 1-4小时为半天，4-8小时为一天；160每天
private Integer tmnNum;
// 单价（元）
private Float unitPrice;
// 金额(元） = gwnNum*120+tmnNum+160
private Float unitAmount;
// 备注
private String notes;
public WorkSheetDetail(String workCtx, Float totalHumanDays, Integer gwnNum, Integer tmnNum, Float unitPrice,
Float unitAmount, String notes) {
super();
this.workCtx = workCtx;
this.totalHumanDays = totalHumanDays;
this.gwnNum = gwnNum;
this.tmnNum = tmnNum;
this.unitPrice = unitPrice;
this.unitAmount = unitAmount;
this.notes = notes;
}
public String getWorkCtx() {
return workCtx;
}
public void setWorkCtx(String workCtx) {
this.workCtx = workCtx;
}
public Float getTotalHumanDays() {
return totalHumanDays;
}
public void setTotalHumanDays(Float totalHumanDays) {
this.totalHumanDays = totalHumanDays;
}
public Integer getGwnNum() {
return gwnNum;
}
public void setGwnNum(Integer gwnNum) {
this.gwnNum = gwnNum;
}
public Integer getTmnNum() {
return tmnNum;
}
public void setTmnNum(Integer tmnNum) {
this.tmnNum = tmnNum;
}
public Float getUnitPrice() {
return unitPrice;
}
public void setUnitPrice(Float unitPrice) {
this.unitPrice = unitPrice;
}
public Float getUnitAmount() {
return unitAmount;
}
public void setUnitAmount(Float unitAmount) {
this.unitAmount = unitAmount;
}
public String getNotes() {
return notes;
}
public void setNotes(String notes) {
this.notes = notes;
}
}
