Conditionally Add Icon And Style On Records In Salesforce Lightning DataTable Component
Scenario – When an account record is marked as important(the custom field checkbox VIP_Account__c is enabled) in the account record detail page, an slds-icon “check” appears in the lightning datatable and the record will be highlighted in red color.
When an account record is marked as not important(the custom field checkbox VIP_Account__c is disabled) in the account record detail page, an slds-icon “close” appears in the lightning datatable and the record will be highlighted in black color.
Prerequisites- Create a custom field in account of type checkbox and give the name – VIP_Account__c.

Styling inside init method is working perfectly but I have a scenario where account data is provided by another component in attribute. Data gets updated in the data table but styling does not apply since component is not rendered and init method is not invoked. Any idea how styling code can be re-run whenever account data inside attribute is changing.
good one
