# Editor example Envelope display with in table controls

This example combines the envelope display controller example with the in table controls example to show a form which is presented in an 'envelope' display, based on controls which are generated links in the table.

Please note that this example specifically uses the DataTables styling, rather than Bootstrap or similar, as the envelope display controller uses styles from the DataTables styling for Editor.

Name | Position | Office | Extn. | Start date | Salary | Edit / Delete
--- | --- | --- | --- | --- | --- | ---
Name | Position | Office | Extn. | Start date | Salary | Edit / Delete

- JavaScript
- HTML
- CSS
- Ajax
- Server-side script

The JavaScript shown below is used to initialise the table shown in this example:

`const editor = new DataTable.Editor({ ajax: '../php/staff.php', display: 'envelope', fields: [ { label: 'First name:', name: 'first_name' }, { label: 'Last name:', name: 'last_name' }, { label: 'Position:', name: 'position' }, { label: 'Office:', name: 'office' }, { label: 'Extension:', name: 'extn' }, { label: 'Start date:', name: 'start_date', type: 'datetime' }, { label: 'Salary:', name: 'salary' } ], table: '#example' }); const table = new DataTable('#example', { ajax: '../php/staff.php', columns: [ { data: null, render: (data) => data.first_name + ' ' + data.last_name }, { data: 'position' }, { data: 'office' }, { data: 'extn' }, { data: 'start_date' }, { data: 'salary', render: DataTable.render.number(null, null, 0, '$') }, { data: null, className: 'center', defaultContent: '<a href="" class="editor_edit">Edit</a> / <a href="" class="editor_remove">Delete</a>' } ], layout: { topStart: { buttons: { text: 'Create new record', action: function () { // Create new record editor.create({ title: 'Create new record', buttons: 'Add' }); } } } } }); // Edit record table.on('click', 'a.editor_edit', function (e) { e.preventDefault(); editor .title('Edit record') .buttons({ label: 'Update', fn: function () { editor.submit(); } }) .edit(e.target.closest('tr')); }); // Delete a record table.on('click', 'a.editor_remove', function (e) { e.preventDefault(); editor .title('Edit record') .message('Are you sure you wish to delete this row?') .buttons({ label: 'Delete', fn: function () { editor.submit(); } }) .remove(e.target.closest('tr')); });`

In addition to the above code, the following JavaScript library files are loaded for use in this example:

The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:

This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:

``

The following CSS library files are loaded for use in this example to provide the styling of the table:

This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.

The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
