Can sharepoint get excel data from sources other than Onedrive or an existing list?

Hello,
I am in the process of building a flow. I am using the 'list rows present in a table' function. When choosing the location for the excel file, is it possible to use a source other than onedrive or an existing sharepoint list?

I can only access the excel file through a link on our network. So far, I haven't been able to link to it. I only seem to be able to if it's a file on my computer or in an existing sharepoint list.

Is sharepoint not capable of this?

Thank you.
