Table: Flawed example in paginator documentation

This issue is created to accompany a pull request fixing the bug.

Describe the bug

The example code for programmatically paginating trough tables, in the isLastPage() function, is flawed because it only works correctly when the amount of items in the table is an exact multiple of the rows per page count.

The issue can be fixed by replacing

return this.customers ? this.first === this.customers.length - this.rows : true;

with

return this.customers ? this.first + this.rows >= this.customers.length : true;

Steps to reproduce the behavior

Implement the example provided on [https://primeng.org/table#paginator], and make sure that the count of items (customers in the example) is not a multiple of the row size. This will result in the isLastPage() never returning true.

Expected behavior

The isLastPage() should return true when on the last page of a paginated table.
