Developing an email marketing, I came across spaces (approximately 1px) that appear between the columns but this spacing only appears at resolutions smaller than 980px.
The code was generated through the Fireworks software and had some modifications made by me afterwards.
I have already used several techniques such as removing border, padding and spacing from the table but it still did not work.

After much research I discovered that the term for this problem is "hairline".
This is a default behavior that occurs on most mobile devices. There is no method of solving it, it is only possible to disguise it by placing the background or borders with the predominant color or background (usually white).
The tip for anyone who is going through this is to avoid creating email marketing that needs to create clippings in images.
