Hello,

I'm building an email that has a three column table layout for events that should have bottom borders underneath each event. However, the layout breaks in Android 6.0 in Gmail and only some of the borders appear.
I have the same issue with bottom borders for another table for News entries, where the border only appear under some of the news stories. I've provided screenshots of the issues:


News Entry

Here is the code for the three column layout:

<table border="0" cellpadding="0" cellspacing="0" align="center" class="columns" style="width: 580px; min-width: 580px; margin-top: 16px; border-collapse: collapse; border: 0px solid transparent;">

    <td width="100%" style="border: 0px solid transparent;">
          <table class="list-mobile" border="0" cellpadding="0" cellspacing="0" style="width: 580px; min-width: 580px; border-collapse: collapse; mso-table-lspace: 0; mso-table-rspace: 0; border: 0px solid transparent;">
