In pagination, I want feature where Numbers are not visible in between?

#set ($pageSize = $core_v2_widget.GetIntValue('pageSize', 15))
#set ($gpageSize = $core_v2_widget.GetIntValue('gpageSize', 15))

#set ($groups = $core_v2_group.List("%{PageIndex = $pageIndex, PageSize = $pageSize, ParentGroupId = $groupId, SortBy = 'LastUpdate', SortOrder = 'Descending', UserId = $core_v2_user.Current.Id }"))

$core_v2_ui.Pager($groups.PageIndex, $groups.PageSize, $groups.TotalCount, "%{PagedContentFile='groupslist.vm}")

I have been trying this code.

and result is < 1 2 3 4 >

but I want only <     >
