How to create a table in an Excel

We need to attach one more namespace OfficeOpenXml.Table, because ExcelTable class belongs to this namespace.

There are two ways to create a table in Excel worksheet.

First, Indirectly access ExcelTableCollection class object by using Tables property of ExcelWorksheet class.

Second, Directly access ExcelTableCollection class object.

The ExcelTable class is responsible for creating a table within the Excel worksheet. In this code, Tables is the property of ExcelWorksheet class. The type of this property is ExcelTableCollection class. This class has an Add() method & it indirectly involved by the property Tables of ExcelWorksheet class & this Add() method return a specific excel table.

By the direct process, we are creating an object of ExcelTableCollection class & the Add() the method of the ExcelTableCollection class returns an object of the ExcelTable class.

The ExcelTable class has Columns[index] property. By using this property, we can assign column with name & index position of excel table.

Here, I used ShowHeader, ShowFilter, ShowTotal, the three boolean properties of the ExcelTable class.

ShowHeader: Responsible for excel table header.
ShowFilter: Responsible for auto filter each & every column of excel table.
ShowTotal: Responsible for excel table footer operations.

Please see the below code.
  1. using(ExcelRange Rng = wsSheet1.Cells["B4:F12"]) {  
  2.     //Indirectly access ExcelTableCollection class  
  3.     ExcelTable table = wsSheet1.Tables.Add(Rng, "tblSalesman");  
  4.     //table.Name = "tblSalesman";  
  5.     //Directly access ExcelTableCollection class  
  6.     ExcelTableCollection tblcollection = wsSheet1.Tables;  
  7.     ExcelTable table1 = tblcollection.Add(Rng, "tblSalesman");  
  8.     //Set Columns position & name  
  9.     table.Columns[0].Name = "Id";  
  10.     table.Columns[1].Name = "Salesman Name";  
  11.     table.Columns[2].Name = "Sales Amount";  
  12.     table.Columns[3].Name = "Country";  
  13.     table.Columns[4].Name = "Date";  
  14.     //table.ShowHeader = false;  
  15.     table.ShowFilter = true;  
  16.     //table.ShowTotal = true;  
  17. }  
How to insert data into the Excel Table Cells?

Here, I used the Value property of ExcelRange class object & assigned a specific data type value as per column name.

Please see the below code.
  1. //[Id] Column  
  2. using(ExcelRange Rng = wsSheet1.Cells["B5"]) {  
  3.     Rng.Value = Convert.ToInt32("1001");  
  4. }  
  5. //[Salesman Name] Columm  
  6. using(ExcelRange Rng = wsSheet1.Cells["C5"]) {  
  7.     Rng.Value = "John";  
  8. }  
  9. //[Sales Amount] Column   
  10. using(ExcelRange Rng = wsSheet1.Cells["D5"]) {  
  11.     Rng.Value = Convert.ToDecimal("700.00");  
  12. }  
  13. //[Country] Columm  
  14. using(ExcelRange Rng = wsSheet1.Cells["E5"]) {  
  15.     Rng.Value = "UK";  
  16. }  
  17. //[Date] Columm  
  18. using(ExcelRange Rng = wsSheet1.Cells["F5"]) {  
  19.     Rng.Style.Numberformat.Format = "mm/dd/yy";  
  20.     Rng.Value = Convert.ToDateTime("08/26/2017");  
  21. } 
The output of the code.
