Using the new dashboard 2.0? How to mimic old table format? Add back Borders? Grid lines? Left Justify table title? Color table title?
Would be really nice to add the above as an example to the documentation, as nice as the dashboard 2.0 is... Transition to it is not that transparent or easy if you liked the older UI features.
What that CSS is IDK (no time to investigate), but it can be done by using a template set to CSS mode, some styles and a sprinkling of magic (or learning about how to specify CSS selectors and how to apply styles - you decide ).
If you liked the table format from dashboard-1, you can try the node @omrid/node-red-dashboard-2-table-tabulator, which uses the same engine & appearance (tabulator) and offers a quantum leap of new functionality (dynamic formatting functions, notifications, data retrieval, dynamic styling, saving current state in NR datastore and more)
