How to implement table controls in dialog?

Follow these steps:
- Create a structure in SE11
- In the program:
  - Declare the structure in the TABLES statement
  - Declare an internal table of the same size of the structure.
  - Declare the table control:
    - CONTROLS <table_control_name> TYPE TABLEVIEW USING SCREEN <screen_number>.
 - In the Screen
  - Insert the table control with the name used in the topic above as <table_control_name>
  - Insert the fields of the structure into the table control
  - declare status_<screen_number> MODULE
  - do a loop statement like this:
  LOOP AT <internal_table> WITH CONTROL <table_control_name>.
    MODULE table_to_screen_<screen_number>.
  ENDLOOP.
- In the PBO
  - describe the number of lines of your internal table to the control:
MODULE status_<screen_number> OUTPUT.
* SET PF-STATUS 'xxxxxxxx'.
* SET TITLEBAR 'xxx'.

- Move the values from the internal table to the structure:
MODULE table_to_screen_<screen_number> OUTPUT.
  move <internal_table_header> to <structure>.
ENDMODULE.

- In the PAI
  - do a loop statement like this
  LOOP AT <internal_table>.
    MODULE screen_to_table<screen_number>.
  ENDLOOP.

MODULE table_to_screen_<screen_number> OUTPUT.
  DESCRIBE TABLE <internal_table> LINES g_lines.

  move <structure> to <internal_table_header>

  IF g_lines < <table_control_name>-current_line.
    APPEND <internal_table>.
  ELSE.
    MODIFY <internal_table> INDEX <table_control_name>.-current_line.
  ENDIF.
ENDMODULE.
