.SYNOPSIS
  Creates HTML table from .NET objects.
.DESCRIPTION
  This is basic cmdlet, as a helper, to build HTML tables for complex HTML content.
  Converts .NET objects into HTML that can be displayed in a Web browser.
  This cmdlet works like "ConvertTo-Html -Fragment" but does not have any of its disadvantages, allowing HTML entities in cells, omiting the first column colons and allowing multi-column tables in the List mode, etc.
  Features:
  - Parameterset autoresolve. There are no predefined parameter sets
  - Input data preprocessor: sorting and filtering
