How to access current row data in dynamic table field template?

Summary:

In a dynamic table field template, how do I access current row data for other fields?

Example: From end_date field template, access start_date from same row for min validation.

Current template:

<template slot="end_dateTemplate"> 
 <oj-input-date value="{{ field.context.item.data.end_date }}">   
 min="I want to access current.row.start_date."  </oj-input-date></template>

Tried: $current.row, $fields.start_date → Errors

In oj-table we can access it using current.row , but how do we achieve this in template section of dynamic layouts?
