We need to attach two more namespace
a) OfficeOpenXml.Table (for Excel Table)
b) OfficeOpenXml.Style (for Excel Table Style)

1) "Show Total" in an Excel Table?
ShowTotal: This property is responsible for showing table footer of excel table. By Default this property is false. It is a boolean property.

using (ExcelRange Rng = wsSheet1.Cells["B4:F12"])
{
ExcelTableCollection tblcollection = wsSheet1.Tables;
ExcelTable table = tblcollection.Add(Rng, "tblSalesman");

table.ShowTotal = true;
}

4) "Totals Row Formula" & "Total Row Label" in an Excel Table?
These two properties are applied in excel table footer position & applicable for specific column index. Both properties are string type.

TotalRowLabel: Showing a label or text under the excel table footer position.
TotalRowFormula: Applying SUBTOTAL() function in excel table footer position.

Excel SUBTOTAL() function syntax has the following arguments:

Here first arguments function_num is defined a specific number & these numbers are pointing to a specific mathematical function. See this below table.

function_num function Name
101 AVERAGE
102 COUNT
103 COUNTA
104 MAX
105 MIN
106 PRODUCT
107 STDEV
108 STDEVP
109 SUM
110 VAR
111 VARP

https://support.office.com/en-us/article/SUBTOTAL-function-7b027003-f060-4ade-9040-e478765b9939

using (ExcelRange Rng = wsSheet1.Cells["B4:F12"])
{
ExcelTableCollection tblcollection = wsSheet1.Tables;
ExcelTable table = tblcollection.Add(Rng, "tblSalesman");

//Add TotalsRowLabel into Excel table Columns
table.Columns[0].TotalsRowLabel = "Total Rows";

//Add TotalsRowFormula into Excel table Columns
table.Columns[1].TotalsRowFormula = "SUBTOTAL(102,[Id])"; //102 = Count
table.Columns[2].TotalsRowFormula = "SUBTOTAL(109,[Sales Amount])"; //109 = Sum
table.Columns[3].TotalsRowFormula = "SUBTOTAL(101,[Profits])"; //101 = Average
}

5) "Totals Row Function" in an Excel Table:
TotalsRowFunction: Doing the same thing as SUBTOTAL() Excel function but in this case, we use RowFunctions enum for mathematics function.

RowFunctions enum

using (ExcelRange Rng = wsSheet1.Cells["B4:F12"])
{
ExcelTableCollection tblcollection = wsSheet1.Tables;
ExcelTable table = tblcollection.Add(Rng, "tblSalesman");

//Add TotalsRowFunction into Excel table Columns
table.Columns[0].TotalsRowLabel = "Total Rows";
table.Columns[1].TotalsRowFunction = RowFunctions.Count;
table.Columns[2].TotalsRowFunction = RowFunctions.Sum;
table.Columns[3].TotalsRowFunction = RowFunctions.Average;
}

Now build & execute this code. The file is (ExcelTable.xlsx) store on D: drive of the computer.
