通过数据判断element-ui的复选框可选或者不可选

<el-table :data="tableData" stripe style="width: 100%; text-align: center" @selection-change="handleSelectionChange">
<!-- checkbox选中框 -->
     <el-table-column type="selection" width="55" :selectable="selectable"></el-table-column>
</el-table>

selectable(row, index) {          
    if(row.status == 1){
        return true
    }else {
        return false
    }
},
