1：element-ui表格高亮預設顏色，在index.min.css中1855行，這裡我改動了一下：

1. /* background: #edf7ff; */
2. background: #20a0ff;
3. color: #ffffff;

<el-table
v-if="supplierList.length>0"
ref="supplierTable"
:data="supplierList"
highlight-current-row
        border
        @current-change=
 
"handleSupplierChange"
style="width: 100%;border-left: 1px solid #eeeeee">
    <el-table-column
align="center"
label="選擇">
        <template scope="scope">
            <el-radio v-model="supplierRadio" :label="scope.row.supplierNo">{{null}}</el-radio>
        </template>
 
    </el-table-column>
    <el-table-column
align="center"
prop="supplierNo"
label="供應商編號">
    </el-table-column>
    <el-table-column
align="center"
prop="name"
label="供應商名稱"
>
    </el-table-column>
</el-table>
