Create a table
Either type /table in the body of your doc, or use the table button in the editor toolbar.
Formatting tables
Select a cell in your table to see the + icon appear to add new rows and columns:
Resize columns
Hover the separator between two columns, drag and hold it to the place you wish
Move a table around
Hover the margin next to the tables & hold the option menu to drag & drop your tables wherever you want in your document.
Other table options
Hover over the three line menu to the left of your table to select the whole thing and copy anchor link (link to the spot where the table lives in your doc), expand to full width, or delete your table.
(If you have certain integrations installed you will also see some additional options.)
