wp_list_table放置不属于数据库的表头和表内容

Question

I'm having hard time with this. I know WP_List_Table will generate the table for you and the get_columns will set the header and footer of the table that came from an array well in most case that came from the database.

What if I have this database table and it's fields

+----------------+
| Field |  Type  |
+-------+--------+
| id    | int    |
+-------+--------+
| name  | varchar|
+-------+--------+

Then in my get_columns function.

function get_columns() {
  $columns = array(
           'id' => 'ID',
           'name' => 'Name'
           );
  return $columns;
}

So with that.. It'll give me html table like this..

+--------------------+
| ID    |  Name      |
+-------+------------+
| 1     |  Foo       |
+-------+------------+
| 2     |  Bar       |
+-------+------------+

BUT (1) how can I add another header and footer that does not belong in the database? I would want to achieve something like this..

+--------------------+--------+
| ID    |  Name      | Option |
+-------+------------+--------+
| 1     |  Foo       | Click  |
+-------+------------+--------+
| 2     |  Bar       | Click  |
+-------+------------+--------+

(2) I would also want to wrap the Click text in a <form> so I can do some actions with it. I don't know how to deal with this. Any help would be much appreciated.

Answer 1

Add the field to your get_columns() function like this:

function get_columns() {
  $columns = array(
           'id' => 'ID',
           'name' => 'Name',
           'cb' => '<input type="checkbox" />'
           );
  return $columns;
}

The cb column is actually a special case and it automatically creates a "select all" checkbox in your table header. Form functionality is built in so, depending on what you want to do, you'd create some actions by overwriting get_bulk_actions() function.
