Get original item in v-data-table(-server) slot?

[jacob-carlborg-apoex]

For a v-data-table and v-data-table-server, what's the proper way to get the original item when using the [item.${string}] slot? This documentation [1] uses item.raw. The next example [2] uses item.value. This example [3] (which uses a different slot) uses item.columns. According to the API documentation, the item that is passed is of type InternalDataTableItem. This type then breaks down to InternalItem, but there's not documentation of what the members of the interface represent.

I put a breakpoint to see what is actually passed to the slot. Here's a screenshot of what's passed for a v-data-table:

I can see that the data is duplicated in five places: item.columns, item.props.title, item.props.value, item.raw and item.value.

For a v-data-table-server it looks like this:

In this case the data is duplicated in three places: item.columns, item.props.title, item.props.value and item.raw. I have no idea what item.value and item.props.value are. I don't recognize that value (21545).

So what's the proper way to get the original item that, ideally, works for both v-data-table and v-data-table-server? I don't want to accidentally rely on internal implementation details.

Here's a snippet of my code:

<template>
  <v-card>
    <v-card-title>{{ t('title') }}</v-card-title>
    <v-card-text>
      <v-data-table-server
        v-model:page="page"
        v-model:items-per-page="pageSize"
        :headers="headers"
        :items="items"
        :items-length="total"
        @update:options="fetch"
      >
        <template #item.transaction_date="{item}">
          {{
            (() => {
              debugger
            })()
          }}
          {{ truncateDate(item.raw.transaction_date) }}
        </template>
      </v-data-table-server>
    </v-card-text>
  </v-card>
</template>

InternalItem needs to be split up into separate interfaces for selects and tables, item.title and item.props don't really make sense for tables. The original item will always be under item.raw though.

Thanks, that was what I was looking for.
