<b>The mobile-stacking test every comparison-table tool fails differently</b>

Forget feature lists. Resize any comparison-table plugin to 375px wide and watch what happens. That single test ranks them faster than any review.

Three failure modes I see:
— Horizontal scroll: table stays wide, user swipes sideways, columns vanish off-screen. Worst for conversions
— Naive collapse: it stacks but loses the header context, so "Yes / No" cells float with no labels
— Card transform: each product becomes a labeled card. The only good answer

Who needs card-transform most:
— Anyone with 60%+ mobile traffic and a 5-plus column spec table
Who can ignore it:
— Two-column "this vs that" tables that fit anyway

Gotcha nobody mentions: card-transform layouts often break your structured-data table semantics, because the markup gets re-flowed by JS. Test rich results separately from the visual.

My pick: tools that re-render to a labeled card per product, not ones that merely shrink fonts.

<b>Bottom line:</b> if it horizontal-scrolls on mobile, it's costing you clicks, period.
