Vue component returning multiple table rows - html

Question

I'm attempting to return two tr elements from a single component v-design-row. I know vue requires the template elements to be wrapped in a div, but I cannot wrap them in a div because of the tag structure html tables require. When I add the second tr in the v-design-row component then vue doesn't render anything.
Can anyone suggest the best method for accomplishing this?
main.vue
<table class="table">
<thead>
<th>Image</th>
<th>Name</th>
<th>Description</th>
<th>Status</th>
<th>Order</th>
<th>Edit</th>
<th>Delete</th>
</thead>
<tbody v-for="catagory in catagories">
<v-catagory-row :catagory="catagory"></v-catagory-row>
<v-design-row v-for="design in catagory.designs" :design="design"></v-design-row>
</tbody>
</table>
v-design-row.vue
<template>
<tr>
<td><img :src="design.image_directory" :alt="design.name"></td>
<td>{{ design.name }}</td>
<td>
<button class="btn btn-secondary" type="button" data-toggle="collapse" :data-target="'#' + design.identifier" aria-expanded="false" :aria-controls="design.identifier">
<i class="fa fa-plus" aria-hidden="true"></i> Show
</button>
</td>
<td>
<div class="switch">
<input :id="'active'+design.id" v-model="design.active" class="btn-toggle btn-toggle-round-flat" type="checkbox">
<label :for="'active'+design.id"></label>
</div>
</td>
<td>
<button class="btn btn-secondary" type="button">
<i class="fa fa-caret-up" aria-hidden="true"></i>
</button>
<button class="btn btn-secondary" type="button">
<i class="fa fa-caret-down" aria-hidden="true"></i>
</button>
{{ design.sort_order }}
</td>
<td>
<button class="btn btn-secondary" type="button">
<i class="fa fa-pencil" aria-hidden="true"></i>
</button>
</td>
<td>
<button class="btn btn-secondary" type="button">
<i class="fa fa-trash" aria-hidden="true"></i>
</button>
</td>
</tr>
<tr>
<td class="p-0" colspan="7">
<div class="collapse" :id="design.identifier">
<div class="p-3">
{{ design.description }}
</div>
</div>
</td>
</tr>
</template>

Answer 1

You are allowed to group row using multiple <tbody> sections like this:
<table>
<thead>
<tr> ... </tr>
</thead>
<tbody>
<tr> ... </tr>
<tr> ... </tr>
</tbody>
<tbody>
<tr> ... </tr>
<tr> ... </tr>
</tbody>
</table>
You can use this in templates by using a <tbody> as the root element:
<template>
<tbody>
<tr> ... </tr>
<tr> ... </tr>
</tbody>
</template>

Answer 2

Since second tr in your v-design-row contains description of design, I'd suggest that this is whole element and it should occupy one row and have its own layout.
Alternatively, you can have a description separately and all other data in component.
Also, statement
vue requires the template elements to be wrapped in a div
is not quite correct. Template can have any root element while it is a single element. So you can have
<template>
<tr>
</tr>
</template>
or even
<template>
<tr v-if="condition == 1">
</tr>
<tr v-else-if="condition == 2">
</tr>
<tr v-else>
</tr>
</template>

You can use vue-fragment library. It allows you to have wrapper that wont actually be rendered.
