We are very excited to announce that the ability to create and tables is now available in Outlook for Mac Insider Fast, starting with the 16.9 (171210) release! Everything that you can do with tables in Microsoft Word, you can now do in Outlook.
In order to insert a table, open a new compose window and click on the Table command in the ribbon.
Once you have inserted the table in the compose area, and your table is selected, you will see two new tabs in the compose window ribbon - Table Design and Layout. Commands in these two tabs will allow you to tailor the table just the way you want to!
We know a lot of users have been waiting patiently for this feature so we are very happy to be able to finally roll this out. We're still ironing out some bugs so if you see an issue or if you just have feedback, please contact us via Help > Contact Support
If you would like to see enhancements and additions to this feature, (or Mac Outlook as a whole), please vote for the idea on our UserVoice site (Help > Suggest a Feature)
