UI给出的设计图是这样的

1 扩展

要求点击运单号，显示更多内容，

element里面给出的例子是有扩展符号的一列，点击来展示

这里我想了下，把这一列隐藏起来了

然后点击的时候用rowClick 这个事件来进行展开，这里也借鉴了下网上搜来的思路

vue代码见下

generateUUID() { //生成唯一编码
    var d = new Date().getTime();
    var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
        var r = (d + Math.random()*16)%16 | 0;
        d = Math.floor(d/16);
        return (c=='x' ? r : (r&0x3|0x8)).toString(16);
    });
    return uuid;
},
rowClick(row, event, column) {

    Array.prototype.remove = function (val) {
        let index = this.indexOf(val);
        if (index > -1) {
            this.splice(index, 1);
        }
    };

    if(column.label == '运单号'){ // 只有点击运单才展开
        Array.prototype.remove = function (val) {
            let index = this.indexOf(val);
            if (index > -1) {
                this.splice(index, 1);
            }
        };

        if (this.entexpands.indexOf(row.id) < 0) {
            this.entexpands= [];
            row.id = this.generateUUID();
            this.entexpands.push(row.id);
        } else {
            this.entexpands.remove(row.id);
        }
    }

},

css部分

.el-table__expand-icon{
  display: none;
}

2 清空搜索

另外这是个Tab切换的表格，如果切换的时候，要刷新表格，之前的排序要清空，这里表上加上了ref="multipleSelection"

tab切换的时候执行 this.$refs.multipleSelection.clearSort();
