[Feature Request] VDataTable Group Ungrouped Values

[dan-whitehouse]

Problem to solve

This feature would allow for all values that do not match the current criteria for grouping to be put in it's own group.

Currently, if I am trying to group on a field called 'type', only records with a value are grouped. Which leaves all null/undefined/empty values ungrouped.

Proposed solution

What I proposing is an additional property on the VDataTable, lets call it group-empty-values that will tell the internal grouping function to group all empty values together in their own group.

export interface Group<T = any> {
  type: 'group'
  depth: number
  id: string
  key: string
  value: any
  items: readonly (T | Group<T>)[]
}

Where items would be full of records that contain null/undefined/empty values for that specific key.
