RH2017 - How safe is it to copy-paste Excel table to RH help topic?

I have about 50 tables in MS Excel. Each table has 20 rows and 4 columns approximately. For single-sourcing it makes sense to use RH as this information will be available in the help output.

How safe and recommended is it to copy-paste from MS Excel 2016 directly to RH topic? I can manually apply the table style to the copied and pasted table. But will it create any problems in the output or any other known issue with this approach?
