我是laravel的新手。我怀疑如何在同一个控制器中调用其他函数并将处理后的值返回到调用它的函数。我尝试过这类似于C语言，但代码不起作用
<v-flex xs12 md6>
<v-data-table :headers="headers" :items="homeTeam" hide-actions class="elevation-1 white">
<template slot="items" scope="props">
<td class="text-xs-right" v-model="gamesheet.number">{{ props.item.number }}</td>
<td v-model="gamesheet.name">{{ props.item.name }}</td>
</template>
</v-data-table>
</v-flex>
