Overview

Disabling a cell makes the cell read-only or non-editable. Both have similar outcomes, with the following differences:

Read-only cell `readOnly: true`	Non-editable cell `editor: false`
Has an additional CSS class (`htDimmed`)	Has no additional CSS class
Copy works, paste doesn't work	Copy-paste works
Drag-to-fill doesn't work	Drag-to-fill works
Can't be changed by `populateFromArray()`	Can be changed by `populateFromArray()`

Read-only grid

You can make the entire grid read-only by setting readOnly to true as a top-level grid option.

<div id="exampleReadOnlyGrid" class="hot "></div>

In many use cases, you will need to configure a certain column to be read-only. This column will be available for keyboard navigation and copying data (Ctrl/Cmd+C). Editing and pasting data will be disabled.

To make a column read-only, declare it in the columns configuration option. You can also define a special renderer function that will dim the read-only values, providing a visual cue for the user that the cells are read-only.

Read-only specific cells

This example makes cells that contain the word "Nissan" read-only. It forces all cells to be processed by the cells function which will decide whether a cell's metadata should have the readOnly property set.

Non-editable cells behave like any other cells apart from preventing you from manually changing their values.

Non-editable columns

In many cases, you will need to configure a certain column to be non-editable. Doing this does not change its basic behaviour, apart from editing. This means that you can still use the keyboard navigation Ctrl/Cmd+C, and Ctrl/Cmd+V functionalities, and drag-to-fill, etc.

To make a column non-editable, declare it in the columns configuration option. You can also define a special renderer function that will dim the editor value. This will provide the user with a visual cue that the cell is non-editable.
