A simple way to adding columns and rows in Datatable
// Create a new Datatable
DataTable dtEmployee = new
DataTable("Employee");
// Define Column
DataColumn DColEmpID = new
DataColumn("Emp_ID",
System.Type.GetType("System.Int32"));
DColEmpID.AllowDBNull = false;
DColEmpID.Caption = "ID";
DColEmpID.AllowDBNull = false;
//Adding Columns
dtEmployee.Columns.Add(DColEmpID);
DataColumn DColName = new
DataColumn("Emp_Name",
System.Type.GetType("System.String"));
DColName.AllowDBNull = false;
DColName.Caption = "Name";
dtEmployee.Columns.Add(DColName);
DataColumn DColDept = new
DataColumn("Department_ID",
System.Type.GetType("System.Int32"));
DColDept.AllowDBNull = false;
DColDept.Caption = "Department_ID";
DColDept.DefaultValue = "1";
dtEmployee.Columns.Add(DColDept);
DataColumn DColSalary = new
DataColumn("Salary",
System.Type.GetType("System.Decimal"));
DColSalary.Caption = "Salary";
DColSalary.DefaultValue = "0.0";
dtEmployee.Columns.Add(DColSalary);
//Add data into columns
dtEmployee.Rows.Add("1", "Jacky", "21",
"5000");
dtEmployee.Rows.Add("2", "Franky", "21",
"7000");
