In your context, create a node 'Employee'. It should have the attributes person, payment, status, submission, return. Let return be of type string. I assume you have a ztable or some ddic structure employee, which does not have the return field.
You code will be on these lines - change it to your requirements anyway. Place the code in a method depending on your requirement of when the data should be displayed.
data: node_emp type ref to if_wd_context_node,
        itab_emp type table of employee,
        wa_emp  type employee,
        itab_node_emp type if_main=>elements_employee,
        wa_node_emp type if_main=>element_employee.
node_emp = wd_context->get_child_node( name = 'EMPLOYEE' ).
<i>* Get data from your API here into itab_emp *</i>
loop at itab_emp into wa_emp.
  move-corresponding wa_emp to wa_node_emp.
  concatenate wa_emp-payment wa_emp-status wa_emp-submission separated by space into wa_node_emp-return.
  append wa_node_emp to itab_node_emp.
endloop.
node_emp->bind_elements( itab_node_emp ).
Here, before the loop, you need to fetch the data into itab_emp using your APIs. Since you have said you want to display the data of multiple columns as is, I have just concatenated them.
In your view layout, have a table and bind the data source to be the context node Employee.
<b>The data types of itab_node_emp, wa_node_emp will differ based on your view name and node name. Use the code wizard to generate your code according to your design time.</b>
Hope this helps.
