Hi @nalani,
Welcome to the Bunnings Workshop community, we are excited to have you with us.
The tabletop is polished concrete, which would be fairly difficult to replicate in look, but with paint you can certainly get close.
I'd suggest filling the dent with Selleys Knead It Multi Purpose Epoxy Putty. Allow it to dry, then give it a light sand to smooth it out.
You'll then have to do your best to paint the filler to match. Head to your local store and grab some colour cards that look close to the colour of your tabletop. Take them home with you to compare them against the table. Pick out the closest colour and head back in store so the team at the Paint Desk can mix you up a sample pot of that colour.
You can then use a craft brush to paint the patch, doing your best to blend it in with the surrounding areas.
Let me know what you think and if you have further questions, please don't hesitate to ask.
Jacob
