The key used to get equal columns (or align data in columns) in a typewriter is the Tabulator Key (or simply the Tab Key).
The Tabulator system in a typewriter consists of:
Tabulator Stops (or tabs) that are set by the typist at specific points along the carriage's path.
The Tab Key (or Tabulator Bar), which, when pressed, quickly moves the carriage to the next preset tab stop, allowing for quick alignment of text or numbers into columns.
On some older or specialized models, you might also find Decimal Tab Keys which are designed to align columns of numbers precisely on their decimal points.
