Tooltip 文字提示，居中显示

Tooltip 文字提示有时候在table中无法居中显示，这个可以设置一下

<a-tooltip
             placement="top"
                  overlayClassName="label-management-tooltip"
                  class="ant_too"
                  :getPopupContainer="
                    (triggerNode) => {
                      return triggerNode.parentNode
                    }
                  "
          >
            <template>
              <div>
               {{name}}
              </div>
            </template>
            <span>
                {{name}}
            </span>
          </a-tooltip>

<style lang="less">

  white-space: break-spaces;
}
</style>

<style lang="less" scoped>
