ASP.NET MVC5+EF6+EasyUI 后台管理系统(88)-Excel导入和导出-主从表结构导出

前言

前面一篇详细讲解了导入导出,本节演示混合结构的导出功能!同时提供代码下载..

先看效果图:这个一个混合的Excel,列表与自定义信息的混合!

  我们的步骤大概分为以下几步

  • 1.模拟数据库数据
  • 2.创建工作簿
  • 3.填充固定数据
  • 4.合并单元格
  • 5.处理动态数据

  数据及环境准备

  创建一个新的Asp.Net MVC5项目,并从Nuget包安装ClosedXML

  

  为了更好的跟真实数据结合,我们需要模拟一些静态数据,新建2个模型来保存数据

  public class SchoolClass
    {

        public string Id { get; set; }//班级标示
        public string Name { get; set; }//班级名称
        public string Manager { get; set; }//班主任姓名
        public string Manager2 { get; set; }//副班主任姓名
        public string PhoneNumber { get; set; }//班主任联系电话
        public string PhoneNumber2 { get; set; }//副主任联系电话
        public string Remark { get; set; } //班级说明
        public List<Students> stuList { get; set; }//一个班级对应多个学生
    }

    public class Students
    {
        public string Id { get; set; }//学号
        public string Name { get; set; }//姓名
        public string Sex { get; set; }//性别
        public string Age { get; set; }//年龄
        public string Point { get; set; }//年度得分
        public string PhoneNumber { get; set; }//电话
    }

注:从模型看出,这是一个班级信息表,一个班级对应多个学生的信息!

实现方式

1.新建一个控制器并填充数据

 public ActionResult Index()
 {
            //模拟数据库赋值,一个班级对应多个学生
            SchoolClass model = new SchoolClass();
            model.Id = "CLS0001";
            model.Name = "三年二班";
            model.Manager = "黄SIR";
            model.PhoneNumber = "13800138000";
            model.Manager2 = "李SIR";
            model.PhoneNumber2 = "13888138666";
            model.Remark = "这是一段有很多个字的班级说明,只有足够长的字,才能证明这段文字很长,如果100个字还不够长,那么就再来100个字!";
            model.stuList = new List<Students>();
            model.stuList.Add(new Students() { Id = "STU0001", Name = "牛掰掰", Sex = "", Age = "23",Point="80", PhoneNumber = "13545678547" });
            model.stuList.Add(new Students() { Id = "STU0002", Name = "张三", Sex = "", Age = "23", Point = "70", PhoneNumber = "13545654874" });
            model.stuList.Add(new Students() { Id = "STU0003", Name = "李四", Sex = "", Age = "25", Point = "50", PhoneNumber = "13545633552" });
            model.stuList.Add(new Students() { Id = "STU0004", Name = "王五", Sex = "", Age = "22", Point = "66", PhoneNumber = "13566885541" });
            model.stuList.Add(new Students() { Id = "STU0005", Name = "林蛋大", Sex = "", Age = "26", Point = "95", PhoneNumber = "13821298458" });
            model.stuList.Add(new Students() { Id = "STU0006", Name = "刘丽丽", Sex = "", Age = "19", Point = "95", PhoneNumber = "13821298458" });

}

 

2.创建作业本并填充表头

红框中表示表示表头位置,我们Excel大家都知道是按位置标示的,比如我点中的三年二班表示的是B3(左上角显示),所有我们填充表头也是这么做

   var wb = new XLWorkbook();
            var ws = wb.Worksheets.Add("班级");
            ws.Cell("A1").Value = model.Name+"班级信息表";
            //标题
            ws.Cell("A2").Value = "班级代号";
            ws.Cell("B2").Value = "班级名称";
            ws.Cell("C2").Value = "班主任";
            ws.Cell("D2").Value = "联系电话";
            ws.Cell("E2").Value = "副班主任";
            ws.Cell("F2").Value = "联系电话";
            //主表内容
            ws.Cell("A3").Value = model.Id;
            ws.Cell("B3").Value = model.Name;
            ws.Cell("C3").Value = model.Manager;
            ws.Cell("D3").Value = model.PhoneNumber;
            ws.Cell("E3").Value = model.Manager2;
            ws.Cell("F3").Value = model.PhoneNumber2;
            ws.Cell("A4").Value = model.Remark;//说明

            //明细表标题
            ws.Cell("A5").Value = "学号";
            ws.Cell("B5").Value = "姓名";
            ws.Cell("C5").Value = "性别";
            ws.Cell("D5").Value = "年龄";
            ws.Cell("E5").Value = "得分";
            ws.Cell("F5").Value = "电话号码";

所以位置决定内容,填充表头后。我们再填充列表

   for (int i = 0; i < model.stuList.Count(); i++)
            {
                ws.Cell(i + 6, 1).Value = model.stuList[i].Id;
                ws.Cell(i + 6, 2).Value = model.stuList[i].Name;
                ws.Cell(i + 6, 3).Value = model.stuList[i].Sex;
                ws.Cell(i + 6, 4).Value = model.stuList[i].Age;
                ws.Cell(i + 6, 5).Value = model.stuList[i].PhoneNumber;
                ws.Cell(i + 6, 6).Value = model.stuList[i].PhoneNumber;
            }

由于我们列表数据是动态并不是固定的,工作簿也是支持二维数组位置填充!看代码从第6行开始,一行一行填充!

3.合并和填充

       var rngTable = ws.Range("A1:F" + (model.stuList.Count() + 5));

            //合并表头
            var rngHeaders = rngTable.Range("A1:F1");
            ws.Row(1).Height = 20;
            rngHeaders.FirstCell().Style
             .Font.SetBold()
             .Fill.SetBackgroundColor(XLColor.Buff)
             .Alignment.SetHorizontal(XLAlignmentHorizontalValues.Center);
            rngHeaders.FirstRow().Merge();

            //第二行表头样式
            rngHeaders = rngTable.Range("A2:F2"); // The address is relative to rngTable (NOT the worksheet)
            rngHeaders.Style.Alignment.Horizontal = XLAlignmentHorizontalValues.Center;
            rngHeaders.Style.Font.Bold = true;
            //rngHeaders.Style.Font.FontColor = XLColor.DarkBlue;
            rngHeaders.Style.Fill.BackgroundColor = XLColor.Aqua;


            //合并说明
            var rngRemark = rngTable.Range("A4:F4");
            ws.Row(4).Height = 30;
            rngRemark.Style.Alignment.WrapText = true;
            rngRemark.FirstCell().Comment.Style.Size.SetAutomaticSize();
            rngRemark.FirstRow().Merge();

            rngTable = ws.Range("A5:F" + (model.stuList.Count() + 5));
            var excelTable = rngTable.CreateTable();

            ws.Columns().AdjustToContents(); 

最后我们要做:填充颜色,合并单元格就好,比如说明:说明内容我们是填充在A4,但是我们要合并A1-F4的位置


 public ActionResult Index()
        {
            //模拟数据库赋值,一个班级对应多个学生
            SchoolClass model = new SchoolClass();
            model.Id = "CLS0001";
            model.Name = "三年二班";
            model.Manager = "黄SIR";
            model.PhoneNumber = "13800138000";
            model.Manager2 = "李SIR";
            model.PhoneNumber2 = "13888138666";
            model.Remark = "这是一段有很多个字的班级说明,只有足够长的字,才能证明这段文字很长,如果100个字还不够长,那么就再来100个字!";
            model.stuList = new List<Students>();
            model.stuList.Add(new Students() { Id = "STU0001", Name = "牛掰掰", Sex = "", Age = "23",Point="80", PhoneNumber = "13545678547" });
            model.stuList.Add(new Students() { Id = "STU0002", Name = "张三", Sex = "", Age = "23", Point = "70", PhoneNumber = "13545654874" });
            model.stuList.Add(new Students() { Id = "STU0003", Name = "李四", Sex = "", Age = "25", Point = "50", PhoneNumber = "13545633552" });
            model.stuList.Add(new Students() { Id = "STU0004", Name = "王五", Sex = "", Age = "22", Point = "66", PhoneNumber = "13566885541" });
            model.stuList.Add(new Students() { Id = "STU0005", Name = "林蛋大", Sex = "", Age = "26", Point = "95", PhoneNumber = "13821298458" });
            model.stuList.Add(new Students() { Id = "STU0006", Name = "刘丽丽", Sex = "", Age = "19", Point = "95", PhoneNumber = "13821298458" });



            var wb = new XLWorkbook();
            var ws = wb.Worksheets.Add("班级");
            ws.Cell("A1").Value = model.Name+"班级信息表";
            //标题
            ws.Cell("A2").Value = "班级代号";
            ws.Cell("B2").Value = "班级名称";
            ws.Cell("C2").Value = "班主任";
            ws.Cell("D2").Value = "联系电话";
            ws.Cell("E2").Value = "副班主任";
            ws.Cell("F2").Value = "联系电话";
            //主表内容
            ws.Cell("A3").Value = model.Id;
            ws.Cell("B3").Value = model.Name;
            ws.Cell("C3").Value = model.Manager;
            ws.Cell("D3").Value = model.PhoneNumber;
            ws.Cell("E3").Value = model.Manager2;
            ws.Cell("F3").Value = model.PhoneNumber2;
            ws.Cell("A4").Value = model.Remark;//说明

            //明细表标题
            ws.Cell("A5").Value = "学号";
            ws.Cell("B5").Value = "姓名";
            ws.Cell("C5").Value = "性别";
            ws.Cell("D5").Value = "年龄";
            ws.Cell("E5").Value = "得分";
            ws.Cell("F5").Value = "电话号码";

   

            for (int i = 0; i < model.stuList.Count(); i++)
            {
                ws.Cell(i + 6, 1).Value = model.stuList[i].Id;
                ws.Cell(i + 6, 2).Value = model.stuList[i].Name;
                ws.Cell(i + 6, 3).Value = model.stuList[i].Sex;
                ws.Cell(i + 6, 4).Value = model.stuList[i].Age;
                ws.Cell(i + 6, 5).Value = model.stuList[i].PhoneNumber;
                ws.Cell(i + 6, 6).Value = model.stuList[i].PhoneNumber;
            }

            var rngTable = ws.Range("A1:F" + (model.stuList.Count() + 5));

            //合并表头

            rngHeaders.Style.Alignment.Horizontal = XLAlignmentHorizontalValues.Center;
            rngHeaders.Style.Font.Bold = true;
            //rngHeaders.Style.Font.FontColor = XLColor.DarkBlue;

                Workbook = wb
            };


        }

总结

代码不难看懂,基本情景我都用到:比如合并、高度、自动换行、等等,是一篇值得参考的文章,同时也见证ClosedXML的强大
