Remove the "_" prefix from your data properties, then it should work. Vue uses underscores for internal stuff, so best avoid using it (see https://v2.vuejs.org/v2/api/#data)

There’s a problem with v-for and tables (ref ‘v-for with 2 every time’) that requires a template wrapper.
See example CodePen.
<div id='app'>
<table>
<template v-for="(employee, key) in employees">
<tr>
<td>{{ employee.first_name }}</td>
<td>{{ employee.last_name }}</td>
</tr>
</template>
<table>
</div>
It also appears that you do need to remove the underscores (try changing employee to _employee in the codepen).
