It is just like when you open a big document in a text editor, you will only see as many lines as your window height is able to accomodate, and to see more lines you will need to scroll down using the adequate keyboard shortcuts.
To scroll down the expansion table, you simply type a digit and it moves the range of the displayed expansions accordingly. Typing 7 for example wil shift the range of the shown expansions, so that the new range starts with the expansion that was previously displayed on line 7:
