scTable selection切换分页清除所选项问题解决记录
- 组件内部根据下图注释部分方法调用
  下方代码中注释的调用为关闭选项清除
  
  //javascript
    //更新数据 合并上一次params
    upData(params, page=1){
        this.currentPage = page;
        // this.$refs.scTable.clearSelection();
        Object.assign(this.tableParams, params || {})
        this.getData()
    },
    //重载数据 替换params
    reload(params, page=1){
        this.currentPage = page;
        this.tableParams = params || {}
        // this.$refs.scTable.clearSelection();
        this.$refs.scTable.clearSort()
        this.$refs.scTable.clearFilter()
        this.getData()
    },

- 使用组件时，组件添加row-key属性，selection类型的列组件添加reserve-selection属性；
  
    <scTable ref="table" :apiObj="apiObj" row-key="id" height="500px" :params="params" @selection-change="selectionChange" stripe>
        <el-table-column type="selection" width="50" reserve-selection></el-table-column>
