title: Hairline borders between my tables in Gmail Android App (Android 5-6)
body: <p>I am going crazy trying to figure out why this happening.  I have hairline borders appearing between my tables in my Gmail App on Android 5-6 on a email template i'm working on for a client. This doesnt appear in any other client but the gmail app. The weird thing is, when I zoom in the hairlines disappear on a specific zoom level.</p>
  
  <p>The hairlines are very light but you can see them in the screenshot</p>

  <p>I have border-collapse:collapse on all tables with cellpadding, cellspacing, border and border-spacing all set to 0.</p>
  
  <p>Any assistance or input anyone could have would be really appreciated.</p>
