Was wondering if anyone has figured out how to integrate the File Preview (for PDFs, jpgs etc.) that is present in the standard Files Related List into Lightning Data Table? i found this link that can open a preview "/sfc/servlet.shepherd/version/renditionDownload?rendition=THUMB720BY480&versionId=0688E0000008paMQAQ" but its not in the same in functionality and layout (ie. doesnt have the Download, Share etc. links). I've seen some uses of lightning:fileCard but not within Lightning Datatable
Create a row action in data table and launch slds modal opener where you can use lightning:fileCard base component to preview a file.
