Tabular data requires a different typographic approach than long-form reading.
Tabular Numerals
Proportional numerals vary in width (a '1' is narrower than an '8'). This causes numbers in a column to stagger, making order-of-magnitude comparisons impossible. Always enable `font-variant-numeric: tabular-nums;` in your CSS.
Monospace vs Sans-Serif
While monospace fonts guarantee alignment, they are often too wide and reduce density. A strong geometric sans-serif with built-in tabular numerals is usually the best choice for financial or operational data.
