树形当文字超出设定宽度时，无法正常显示

使用标签的title属性

<el-tree:data="comTreeList"ref="tree"class="showtree":props="props":load="loadNode"lazyaccordion@node-click="handleNodeClick"><spanslot-scope="{ node }":title="node.label"v-text="node.label"></span></el-tree>

设置样式

.showtree {font-size: 14px;::v-deep .el-tree-node__content {width: 200px;overflow: hidden;white-space: nowrap;text-overflow: ellipsis;display: block;}}
