Using variables for html styling

Since Variable values are substituted at run-time, not only can a variable contain data, but it can contain an HTML snippet.

For example it can contain inline styling in order to dynamically apply different styling at run-time.

One example is to show or hide a section of HTML based on business logic.

The code in the Email Data User-Exit will be like the following:

                        
                            
                                1:
2:
3:
4:
5:
6:

                                    IF l_hide = 'X'.
        ls_variables-var_code = 'SHOW_HIDE'.
        ls_variables-value = ' style="display:none;"'.
        ls_variables-row_num = l_row_num.
        APPEND ls_variables TO ch_variables.
    ENDIF.
                            

                    

Within the HTML Block, the variable is used as follows:

                        
                            
                                1:
2:
3:
4:
5:
6:
7:
8:
9:
10:
11:
12:
13:
14:

                                <tr&SHOW_HIDE&>
    <td style="border-bottom:3px solid #9BBB59;">
    <p style="font-family:'Segoe UI',Helvetica,sans-serif;width:100%;color:#545454;font-weight:bold;font-size:12px;
margin-top:0px;margin-bottom:0px;">
      Confirmed Date
    </p>
  </td>
  <td style="border-bottom:3px solid #9BBB59;"align="center">
    <p style="font-family:'Segoe UI',Helvetica,sans-serif;width:100%;color:#545454;font-weight:bold;font-size:12px;
margin-top:0px;margin-bottom:0px;">
      Qty
    </p>
  </td>
  </tr>
                            

                    

Either the variable will be blank, in which case the table row will be displayed, or it will contain styling, in which case the table row will be hidden.
