In order to avoid duplication of markings for several layers, a directive could be applied in the template. v-for♪A little difficulty in the component v-data-table Use the dynamic names of the table ' s, in format header.<name> and item.<name> - Where? vername is the identity of the data facility (element) items)The problem of content falling into the default slope arose in the question code only because of the transmission as a name of the elephant of the data facility, instead of the expected "put" component.
We need to use the template. computed Name of each elephant participating in the bulkhead:<template v-for="prop in itemProps"
v-slot:[`item.${prop}`]="{ item }"
>
<div class="d-flex flex-column" :key="prop">
<b>{{ item[prop] }}</b>
<span>{{ item[prop] }}</span>
</div>
</template>
Massives with recalibration properties (named) itemProps In the example above, a literary may be placed or may be derived from the structure of the headings of the table (propose that the component is represented by a mass headerscomputed: {
itemProps() {
return this.headers.map(header => header.value);
},
// ...
