If I copy and past from Excel I only get the texted.
If I click on the table button I get the code and have to go to each [ td ][ /td ] and type. I just noticed that the table properties, delete table, add rows/columns buttons are not usable.
[table="width: 500, class: grid"]
[tr]
[td]type data here[/td]
[td][/td]
[/tr]
[tr]
[td][/td]
[td][/td]
