You can use markdown to create a table. See Add a table to your post using markdown.
If you don’t want to learn the syntax, you can use an online tool like this or paste a table.

Ever tried to copy a spreadsheet into Discourse to find that you just get plain text? No longer! We now support pasting tables from common spreadsheet programs like Excel, Numbers, and Libre Office and generating a Markdown table.
