Renders a vertical left-side tab navigation with associated sub-report content panels.
BigTable — set as ReportType in def_report.
def Render(self, Param1="", Param2="", Param3="", Orientation="") -> str:
Param2 / Param3 — passed through to each embedded sub-report.
Returns a two-column Bootstrap layout: a col-md-2 vertical nav-tabs list on the left and a col-md-10 tab-content panel on the right. The query must return at least two columns per row: tab label (column 1) and report code (column 2); an optional third column provides the sub-report's Param1. An optional fourth column in the first row (Data[0][3]) may contain a raw HTML "plus" element appended after the tab list. The active tab is determined by self._LastTab. Includes lazy-load refresh on tab show.
Requires bootstrap.vertical-tabs.css. Unlike ObjReportVpills, this variant uses nav-tabs instead of nav-pills and supports an inline "plus tab" HTML element.
