/**

29 |
* A component that renders the default column header in a form.
|
|
30 |
*
|
|
31 |
* If the current column is sortable, it renders the header as a link.
|
|
32 |
* Clicking on the link causes the table to be sorted on that column.
|
|
33 |
* Clicking on the link again causes the sorting order to be reversed.
|
|
34 |
*
|
|
35 |
* This component renders links that cause the form to be submitted.
|
|
36 |
* This ensures that the updated data in the other form fields is preserved.
