Function getPageGroupings

getPageGroupings(
    pageNumber: number,
    totalPages: number,
    options?: PageGroupingOptions,
): number[][]
Returns groups of page numbers for pagination purposes (e.g. "Jump to Page" type buttons).

If options are provided but exclude a value for boundaryPadding, a default will be computed based on the value of currentPagePadding. This default should be used as it leads to a constant number of page numbers regardless of the current page (to avoid buttons jumping around).
Parameters
- pageNumber: number
  The index of the current page (zero-indexed).
- totalPages: number
  The total number of pages available.
- Optionaloptions: PageGroupingOptions
  Options for display. (default: {currentPagePadding: 2, boundaryPadding: 5}).
Returns number[][]
