In our e-commerce development system, there is usually a list displayed in the form of tree, such as the following picture

 <tree-table
        class="treeTable"
        :data="catelist"
        :columns="columns"
        :selection-type="false"
        :expand-type="false"
        show-index
        index-text="#"
        border
        :show-row-hover="false"
      >
      </tree-table>
:data="catelist" Specifies the list of bound data :columns="columns" Specifies the name of the column for the table

After binding the above two properties, the effect is achieved ~
