Salesforce provided an example on how to do Data Table with Inline Editing (https://developer.salesforce.com/docs/component-library/documentation/lwc/data_table_inline_edit) capability.  When displaying a related field in the datatable column, it displays the ID instead of the relatedObject.Name.

For example, if I have a field Assignee__c that is related to the User object.  When displaying the Assignee__c field in the data table, it only displays the ID of the Assignee__c instead of the look up field that we can search and select a new user.

Does anyone know how to get around this?

Thanks,
Brianwx
