# Editor example FixedColumns integration

Editor's inline editing mode also supports the FixedColumns extension for DataTables. FixedColumns allows one or more columns to be frozen in place at the edges of a scrolling table, while still remaining inline editable, as shown in this example. Simply click on the cell to edit it.

This example also demonstrates the ability of the Select extension to operate with the fixed columns, allowing the row to be selectable from the checkbox regardless of horizontal scrolling position.

| First name | Last name | Position | E-mail | Office | Extn. | Age | Start date | Salary
--- | --- | --- | --- | --- | --- | --- | --- | --- | ---

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

`var editor = new DataTable.Editor({ ajax: '../../controllers/staff.php', fields: [ { label: 'First name:', name: 'first_name' }, { label: 'Last name:', name: 'last_name' }, { label: 'Position:', name: 'position' }, { label: 'E-mail:', name: 'email' }, { label: 'Office:', name: 'office' }, { label: 'Extension:', name: 'extn' }, { label: 'Age:', name: 'age' }, { label: 'Start date:', name: 'start_date', type: 'datetime' }, { label: 'Salary:', name: 'salary' } ], table: '#example' }); var table = $('#example').DataTable({ ajax: '../../controllers/staff.php', buttons: [ { extend: 'create', editor: editor }, { extend: 'edit', editor: editor }, { extend: 'remove', editor: editor } ], columns: [ { // Checkbox select column data: null, defaultContent: '', className: 'select-checkbox', orderable: false }, { data: 'first_name' }, { data: 'last_name' }, { data: 'position' }, { data: 'email' }, { data: 'office' }, { data: 'extn' }, { data: 'age' }, { data: 'start_date' }, { data: 'salary', render: DataTable.render.number(null, null, 0, '$') } ], dom: 'Bfrtip', fixedColumns: { leftColumns: 2 }, order: [1, 'asc'], scrollX: true, select: { style: 'os', selector: 'td.select-checkbox' } }); // Activate an inline edit on click of a table cell $('#example').on('click', 'tbody td:not(:first-child)', function (e) { editor.inline(this); });`
`const editor = new DataTable.Editor({ ajax: '../../controllers/staff.php', fields: [ { label: 'First name:', name: 'first_name' }, { label: 'Last name:', name: 'last_name' }, { label: 'Position:', name: 'position' }, { label: 'E-mail:', name: 'email' }, { label: 'Office:', name: 'office' }, { label: 'Extension:', name: 'extn' }, { label: 'Age:', name: 'age' }, { label: 'Start date:', name: 'start_date', type: 'datetime' }, { label: 'Salary:', name: 'salary' } ], table: '#example' }); const table = new DataTable('#example', { ajax: '../../controllers/staff.php', buttons: [ { extend: 'create', editor }, { extend: 'edit', editor }, { extend: 'remove', editor } ], columns: [ { // Checkbox select column data: null, defaultContent: '', className: 'select-checkbox', orderable: false }, { data: 'first_name' }, { data: 'last_name' }, { data: 'position' }, { data: 'email' }, { data: 'office' }, { data: 'extn' }, { data: 'age' }, { data: 'start_date' }, { data: 'salary', render: DataTable.render.number(null, null, 0, '$') } ], dom: 'Bfrtip', fixedColumns: { leftColumns: 2 }, order: [1, 'asc'], scrollX: true, select: { style: 'os', selector: 'td.select-checkbox' } }); // Activate an inline edit on click of a table cell table.on('click', 'tbody td:not(:first-child)', function (e) { editor.inline(this); });`

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.
