the interface looks like this:

the list data given by the backend looks something like this:

[
    {
        top:0, //
        down:0, //
        scale:0, //
        ruleUid:1, //id
    },
    {
        top:0, //
        down:0, //
        scale:0, //
        ruleUid:2, //id
    },
]

where rounding rules the data of the drop-down box is given by the backend:

[    
    {
        uid:1,
        name:"-"
    },
    {
        uid:2,
        name:"-"
    },
    {
        uid:3,
        name:"-"
    },
]

my code:

<el-table-column prop="ruleUid" label="">
    <template slot-scope="scope">
        <el-select 
            v-model="value_regular"
            style="width:120px"
            size="small">
            <el-option 
                v-for="item in list_regular"
                :label="item.name"
                :value="item.uid"
                :key="item.uid">
            </el-option>
        </el-select>
    </template>
</el-table-column>

my question:
the list may have 1 line, 2 lines, 3 lines. There are n drop-down boxes on the n-line. However, I only define one variable, vmurmodel = "value_regular". How can I set this variable to be dynamic? That is, a variable stores a drop-down box so that I can easily pass the value when I submit it. Or is there a good solution?
