While working with tables in DsExcel .NET, you can configure it as per your spreadsheet requirements by modifying the table using the properties and methods of the ITable interface.
DsExcel .NET allows you to modify the table range of your worksheet using the Resize method of the ITable interface.
Refer to the following example code to modify table range.

//Modify table range table.Resize(worksheet.Range["B1:E4"]); |
You can modify the value of specific table areas by accessing its header range, data range and total range using the HeaderRange property, DataRange property and TotalsRange property of the ITable interface.
Refer to the following example code to modify table areas in your worksheet.

ITable table = worksheet.Tables.Add(worksheet.Range["A1:E5"], true); table.ShowTotals = true; //Populate table values worksheet.Range["A2"].Value = 3; worksheet.Range["A3"].Value = 4; worksheet.Range["A4"].Value = 2; worksheet.Range["A5"].Value = 1; worksheet.Range["B2"].Value = 32; worksheet.Range["B3"].Value = 41; worksheet.Range["B4"].Value = 12; worksheet.Range["B5"].Value = 16; worksheet.Range["C2"].Value = 3; worksheet.Range["C3"].Value = 4; worksheet.Range["C4"].Value = 15; worksheet.Range["C5"].Value = 18; //Table second column name set to "Age". worksheet.Tables[0].HeaderRange[0, 1].Value = "Age"; //"Age" Column's second row's value set to 23. worksheet.Tables[0].DataRange[1, 1].Value = 23; //"Age" column's total row function set to average. worksheet.Tables[0].TotalsRange[0, 1].Formula = "=SUBTOTAL(101,[Age])"; |
When you need to make changes to the total row's calculation function of a specific table column, you can use the TotalsCalculation property of the ITableColumn interface.
Refer to the following example code to modify column total row's calculation function.

worksheet.Tables.Add(worksheet.Range["A1:C5"], true); worksheet.Tables[0].ShowTotals = true; //Populate table values worksheet.Range["A2"].Value = 3; worksheet.Range["A3"].Value = 4; worksheet.Range["A4"].Value = 2; worksheet.Range["A5"].Value = 1; worksheet.Range["B1"].Value = 13; worksheet.Range["B2"].Value = 32; worksheet.Range["B3"].Value = 41; worksheet.Range["B4"].Value = 12; worksheet.Range["B5"].Value = 16; worksheet.Range["C1"].Value = 1; worksheet.Range["C2"].Value = 3; worksheet.Range["C3"].Value = 4; worksheet.Range["C4"].Value = 15; worksheet.Range["C5"].Value = 18; //First table column's total row calculation fuction will be "=SUBTOTAL(101,[Column1])" worksheet.Tables[0].Columns[1].TotalsCalculation = TotalsCalculation.Count; |
