Have you ever built multiple lightning-datatable components — one for Accounts, one for Contacts, and yet another for custom objects — each time duplicating the same logic?
What if you could build one reusable lightning datatable that can display any object’s data dynamically, with automatic column generation, search, pagination, and toast messages?
In this blog, we’ll build a fully dynamic, metadata-driven Data Table in LWC that works for any Salesforce Standard or Custom Object — without changing a single line of front-end code.
Key Features:
- Works for any SObject (Standard or Custom)
- Dynamic SOQL and field validation in Apex
- Auto-generated columns with correct labels and field types
- Client-side search
- Client-side pagination (10 records per page)
- Toast notifications for success, errors, and no records
- Graceful “No records found” message
Architecture Overview:
- Apex Controller: Accepts a dynamic request (object name, fields, conditions, limit) and returns metadata + records.
- Parent LWC: Calls Apex, handles success/error toasts.
- Child LWC: Displays data dynamically with search and pagination.
Step 1: Apex Controller – DynamicDataTableController.cls
We’ll create a single, flexible Apex class that accepts any object, any fields, and returns both the data and column metadata.
Step 2: Parent LWC – UniversalDataWrapper
This LWC sends the JSON request to Apex and handles toast notifications.
universalDataWrapper.js
universalDataWrapper.html
universalDataWrapper.xml
Step 3: Child LWC – Reusable Data Table
reusableDatatable.js
reusableDatatable.html
reusableDatatable.xml
How It Works:
- Parent LWC sends a JSON request → Apex
- Apex Controller dynamically validates fields, constructs SOQL, enforces FLS, and returns data + metadata
- Child LWC:
- Auto-builds columns using metadata
- Displays 10 records per page
- Filters results instantly on search
- Shows “No records found” when applicable
UI Preview:
Example JSON Inputs:
Final Output:
- Works for any object
- Auto column generation
- Search & pagination
- Success, info, and error toasts
- Graceful empty state
Next-Level Enhancements:
- Add server-side pagination using OFFSET
- Add sorting via onsort in <lightning-datatable>
- Add export to CSV for filtered data
- Add UI controls to select objects and Fields dynamically
Conclusion:
With this approach, you’ve built a universal, reusable LWC data table that’s fully metadata-driven, dynamic, secure, and user-friendly.
No more duplicating components for each object — this one solution can power any list view, admin dashboard, or configuration UI.
- This design pattern can easily evolve into a managed utility component or developer productivity accelerator inside your Salesforce org.
