There is now Numbers function that can do this. You can, however,
use the contextual menu for each row to insert a single row:
the key command is <option>+<up arrow> or <option>+<down arrow>
and finally you can use the table size controls to change the number of rows (shown below), columns (control at top-right), or rows and columns (control at bottom-right):

Select as many rows as you want to add.
Go Table (menu) > Add Rows Below (or Add Rows Above).
Numbers will insert as many rows as you have selected, placing theme immediately below the bottom row selected (or immediately above the top row selected).
