How to render component labels in string form in vue?

<div id="app">
    <el-form v-model="form" label-width="100px" class="process-edit-form">
        <el-form-item v-for="item in formParams" :label="item.name + ":"">
            <!--  item.html-->
        </el-form-item>
    </el-form>
</div>

var app = new Vue({
    el: "-sharpapp",
    data: {
        button: "<el-button type="primary"></el-button>",
        form: {
            name: "",
            age: ""
        },
        formParams: [
            {name: "", type: "name", html: "<el-input v-model.trim="form.name"></el-input>"},
            {name: "", type: "age", html: "<el-input v-model.trim="form.age"></el-input>"},
        ]
    },
    mounted() {
        this.$nextTick(function () {
            this.$forceUpdate();
        })
    }
})

because I want to dynamically render the component according to the data returned by the background, send me such a string, in what way can it be implemented?
renders this label with v-html, not the component.
