Here's the procedure I used to convert a Numbers table to an Evernote table on my MacBook Pro running Yosemite. Cutting and pasting the table did not work.
Open Numbers spreadsheet
Copy table to be moved to Evernote
Open Text Edit
Create a new Rich Text document
Paste the table into the new document
Save the Textedit document as HTML
Open HTML in Safari
Copy Table in Safari
Paste into Evernote.
