The conclusion obtained by the PS intercept screen
When setting td{height:22px, the page displays: IE is 22px, FF is 21px; The practice proves that IE will always have a big 2px,ff 1px less.
When setting td{line-height:22px}, the page shows: IE is 24px; FF is 24px; it's a lot more 2px than it is, but it stays the same.
You can also measure it yourself.
