Doesn't seem to appear if you minify the output. Can you confirm ?

It looks like a weird bug with vertical-align: middle

Web Gmail I don't see this extra pixel but I see it on Apple email with gmail setup and Outlook.

Outlook 2016 and 2019 does the same

the whiteline should disappear when playing with font size value/ line height and other thing

And iOS mail / gmail same :

Closing this. I was able to fix it by changing the width percentage slightly and it'll disappear.

Example 50% 50% column shows a line and changing it to 49% 51% column removes the line.
