how to use datatable with datagrid view

I have predefined grid view it's contain two column (colEmpCode,colEmpName) those column name are assign by object properties
 
this is my code
 

OdbcCommand OpenEmp = new OdbcCommand("SELECT EMPLOYEE_GROUP_ASSIGN.EmpNo, EMPLOYEE_PERSONAL.FullName FROM " +  
                    "EMPLOYEE_GROUP_ASSIGN INNER JOIN EMPLOYEE_PERSONAL ON EMPLOYEE_GROUP_ASSIGN.EmpNo = EMPLOYEE_PERSONAL.EmpId " + 
                    "WHERE (EMPLOYEE_GROUP_ASSIGN.EmpGroupCode = '" + cmbEmpGrup.Text.Trim().ToString() + "')", MainMod.Conn);
                OdbcDataReader readEmp = OpenEmp.ExecuteReader();
                
                DataTable table = new DataTable();
                table.Columns.Add("EmpNo", typeof(string));
                table.Columns.Add("FullName", typeof(string));
                while (readEmp.Read())
                {
                    table.Rows.Add(MainMod.NullableString(readEmp.GetValue(0).ToString()),MainMod.NullableString(readEmp.GetValue(1).ToString()));
                }
                readEmp.Dispose();
                gvEmployee.DataSource = table;  

 
when i call (gvEmployee.DataSource = table) it give me record to new columns
in data grid view
but i want to add the records to my predefined columns like this
 

gvEmployee.columns[0].value = table.columns[0].value  // this is what i expting 
gvEmployee.columns[1].value = table.columns[1].value

 
how to achieve the target ?
