Add ability to get current filtered items in CDataTable

[CVeniamin]

After looking at the docs CDataTable does not have an event that indicates what are the current filtered items after one applies a filter to a specific column or searched in a table.

Hence, after looking at the code I saw that this can be easily achieved by emitting an event after

coreui-vue/src/components/table/CDataTable.vue

Line 455 in 2ced24b

this.$emit('update:column-filter-value', this.columnFilterState)

and

coreui-vue/src/components/table/CDataTable.vue

Line 463 in 2ced24b

this.$emit('update:table-filter-value', this.tableFilterState)

for instance

this.$emit('update:table-items', this.currentItems)

The name of the new event is mere indicative.

Hi! Thank you for this idea!
What are the cases for using such an event?

Btw. 'currentItems' are not filtered items, but visible items. You probably meant 'tableFiltered' or 'sortedItems' (filtered items after applied sorting).

You are right! Was about to edit the issue since I saw that currentItems are the items visible items as you mentioned...

One of the use cases would be to allow "download" the filtered items to a xlsx/csv file.
I think this can also be achieved through using v-model on a CDataTable instead of an event but requires more code refactoring.

Very useful use-case! We will add this feature :)
