Displaying a b-table with different arrays inside other arrays in Bootstrap.vue

I have some data I'm trying to display in a b-table

It works fine with most data, but when I hit another array inside the referenced array, it doesn't render properly.

So I tripped over this markup

<template v-slot:cell(name)="data">
   <b class="text-info">{{ data.value.last.toUpperCase() }}</b>, <b>{{ data.value.first}}</b>
</template>

From bootstraps' table documentation.

That's great! Unfortunately, I can't get data out properly.

The issue is that the data contains different types of arrays depending on what is being used:

"range": {
        "type": "point",
        "distance": {
           "type": "touch"
         }
},

and

"range": {
     "type": "point",
      "distance": {
       "type": "feet",
       "amount": 150
    }
},

So I can easily retrieve the type variable, as it's always there, but in case distance.type and distance.amount exists, I'd want to display that as well. Unfortunately this causes an error - because sometimes it doesn't contain amount.

<b-table striped hover :items="spells">
   <template v-slot:cell(range)="rangeData">
      <b class="text-info">
         {{rangeData.item.range.distance}}, <--- this displays the content of the problematic array
         {{rangeData.item.range.distance.feet}}, <-- this causes undefined errors and fails to load
         {{rangeData.item.range.type}}  <--- this displays properly
     </b>
   </template>
</b-table>

So a solution I was hoping to find, was to make a conditional field, which checks if the data is reachable, if not, don't display anything. But I can't find any answers or documentation for it.

Wrapping distance.feet in a v-if still causes errors and then doesn't display anything.

According to your question, you are trying to use condition to show data if available otherwise you don't want to show.

For that you simply have do as below-

<b class-"text-info">
   {{rangeData.item.range && rangeData.item.range.distance ? rangeData.item.range.distance: "" }},
   {{rangeData.item.range && rangeData.item.range.distance && rangeData.item.range.distance.feet ? rangeData.item.range.distance.feet: "" }},
   {{rangeData.item.range && rangeData.item.range.type ? rangeData.item.range.type: "" }}
