tab­fig­ures – Main­tain ver­ti­cal align­ment of fig­ures

Knuth de­signed his orig­i­nal fonts with tab­u­lar fig­ures (fig­ures whose width is uni­form); this makes some lay­out prob­lems rather sim­ple. In more re­cent times, fonts (such as Min­ion Pro), which of­fer pro­por­tion­ally spaced fig­ures, are in­creas­ingly be­ing used.
The pack­age pro­vides mech­a­nisms whereby such pro­por­tional fig­ures may still be aligned in tab­u­lar style (for ex­am­ple, in the ta­ble of con­tents).
