DataTable deselect method should have an optional rowIndex parameter

[RyanDubowsky]

Is your feature request related to a problem? Please describe.
It would be helpful to be able to deselect one or more specific rows from the DataTable, rather than all of them (which is the current behavior of deselect).

Describe the solution you'd like
To allow for the user to specify one or more rowIndex they would like to deselect from the table.

Describe alternatives you've considered
Directly modifying the DOM gets very messy very fast.

Additional context
Separately, the documentation for DataTable should be updated to include the deselect method, even if no functionality is added.

Started to do this and decided it was not very Vue. Instead added the ability to use v-model with the table.

<cv-data-table
. . .
  v-model="rowSelects"
. . .
</cv-data-table>

<script>
. . .
data() {
  // rowSelects contains values of rows selected.
  return { rowSelects: [] }; 
}

methods: {
  onMyBatchClick() {
    // do stuff
    this.rowSelects = []; // or slice specific row values.
  }
}
</script>

Let me know if this works for you.

Using v1.0.2 https://codepen.io/lee-chase/pen/YgVoXR

It would appear that the table requires Vue version 2.6.1 as a minimum possible due to vuejs/vue#9330 as nothing else looks like it would impact on this issue 2.6.0 - 2.6.1
