Debug Information

• .z-grid-header, .z-grid-body has fixed width and cause this issue.
  <div id="z_2-head" class="z-grid-header" style="display: none; width: 1668px;">
• since Grid is implemented by <table>, there might be historical reason. Be careful to break the existing features.

Workaround

@media print{
    .z-grid-header, .z-grid-body{
        width:auto!important;
    }
}
