As in in Excel. Shows a dialog where the user enters a (visible/filtered) row number and/or column name. Scrolls to, and selects where appropriate, that cell/row/column.
Ctrl+G shortcut.
Might also be useful to include a "next matching value" option. You enter some search text, and the table view selects the next matching cell in a left-to-right-then-down direction.
Useful when you're editing and don't want to filter?
