Inline Editing

In plain words: The standard Salesforce <lightning-datatable> supports inline editing for text, numbers, and dates out of the box. However, it does not natively support standard lookup search widgets (like picking an Account or a Contact) inside table cells. To add inline editing for relationship fields, you must combine standard datatable draft values with custom cell custom data types or specialized wrapper solutions. Building high-productivity user interfaces in Salesforce often means letting users edit multiple records directly inside a table without clicking into individual detail pages. While text fields are easy to make editable, relationship lookup fields require a bit more architectural planning. In this guide, we will explore how to set up inline editing for datatables and handle record updates using the Lightning UI API.

💬 In plain words: Inline editing in a Salesforce Lightning Web Component (LWC) datatable gives users an Excel-like experience. Instead of opening a separate edit page for every record, users can double-click table cells, type in new values, and save multiple records at once. The table batches all these unsaved changes into a temporary list called draftValues until the user hits the Save button on the bottom banner. Standard Salesforce data grids support basic text, phone, and number editing right out of the box. However, taking it to the next level—like adding dynamic picklist dropdowns inside table cells—requires combining Apex schema methods with custom LWC data types. Let's break down exactly how to build a scalable, editable datatable from scratch.
