element ui的树形组件el-tree使用的注意事项

 

                  <el-tree
                      :data="data6"
                      node-key="id"
                      :props="defaultProps"
                      default-expand-all
                      @node-drag-start="handleDragStart"
                      @node-drag-enter="handleDragEnter"
                      @node-drag-leave="handleDragLeave"
                      @node-drag-over="handleDragOver"
                      @node-drag-end="handleDragEnd"
                      @node-drop="handleDrop"
                      draggable
                      :allow-drop="allowDrop"
                      :allow-drag="allowDrag">
                  </el-tree>

绑定了data属性，还需要指定props，否则加载不出内容
