删除小部件后如何定位jquery gridster？

Question

我可以删除小部件，但我在定位剩余小部件时遇到了问题。

当我从顶部删除一个小部件时，底部小部件会自动移到顶部，看起来不错。但是当我从左边移除一个小部件时，右边的小部件不会被移到左边？

我终于解决了这个问题

<div class="gridster">
    <ul>
      <li data-row="1" data-col="1" data-sizex="2" data-sizey="2">0<span class="removeWidget">X</span></li>
      <li data-row="1" data-col="3" data-sizex="1" data-sizey="2">1<span class="removeWidget">X</span></li>
      <li data-row="1" data-col="4" data-sizex="1" data-sizey="1">2<span class="removeWidget">X</span></li>
      <li data-row="3" data-col="2" data-sizex="3" data-sizey="1">3<span class="removeWidget">X</span></li>
      <li data-row="4" data-col="1" data-sizex="1" data-sizey="1">4<span class="removeWidget">X</span></li>
      <li data-row="3" data-col="1" data-sizex="1" data-sizey="1">5<span class="removeWidget">X</span></li>
