反选逻辑情况下，需要先toggleRowSelection数据，再给 tableData赋值，才能正常选中。
正选情况下，toggleRowSelection，必须从选择tableData中toggleRowSelection Item才能选中。
<el-table
ref="multiTable"
:data="dataList"
stripe
row-key="id"
@selection-change="selectionChange"
>
<el-table-column prop="id" label="模板ID" min-width="150">
</el-table-column>
<el-table-column
align="center"
:reserve-selection="true"
type="selection"
width="85"
>
</el-table-column>
</el-table>
