Correct way to display row name/label

I want to display label (or name) for second row in a table so users know about what that row contains, please see image.

Please note: On left there is another grid, thus adding name/label for the row on left isn't possible.

A solution, I think of is to add a legend along side table name text with background similar to the row (similar to colored legends for charts). Although, not sure if that will help.

Please suggest or provide feedback to make it better. Thank you so much!
