Debug Information

• caused by wrapped texts
• ZK-3748 doesn't fix this case
• suggest applying a CSS declaration instead of a inline style on elements
  current:

  <td id="z_i-chdextr" style="text-overflow: ellipsis;white-space: nowrap;" class="z-row-inner">...</td>
  

  suggested:

  <td id="z_i-chdextr" class="z-row-inner z-row-hidden-column">...</td>
  

workaround

• use <if> to make a column invisible
• apply white-space: nowrap; on a hidden column
• .z-grid .z-row-content { white-space: nowrap; /* overflow: auto; optional, depends on your design */ }
• apply attached js patch
