Parameters: 	-- |1=					— required; The title of the article where the Episode Table is located at. 	-- |EpisodeNumber=		— suggested; The overall episode number in the series. 	-- |EpisodeNumber2=		— suggested; The episode number in the season. 	-- |Title=				— suggested; The English title of the episode. 	-- |RTitle=				— optional; Unformatted parameter that can be used to add a reference after "Title", 											or can be used as a "raw title" to replace "Title" completely. 	-- |AltTitle=			— optional; An alternative title, such as the title of a foreign show's episode in its native language, 											or a title that was originally changed. 	-- |TranslitTitle=		— optional; The title of the episode transliteration (Romanization) to Latin characters. 	-- |RAltTitle=			— optional; Unformatted parameter that can be used to add a reference after "AltTitle", 											or can be used as a "raw title" to replace "AltTitle" completely. 	-- |NativeTitle=		— optional; The title of the episode in the native language. 	-- |NativeTitleLangCode — optional; The language code of the native title language. 	-- |Aux1=				— optional; General purpose parameter. The meaning is specified by the column header. 										This parameter is also used for Serial episode titles, such as those used in Doctor Who. 	-- |DirectedBy=			— optional; Name of the episode's director. May contain links. 	-- |WrittenBy=			— optional; Primary writer(s) of the episode. May include links. 	-- |Aux2=				— optional; General purpose parameter. The meaning is specified by the column header. 	-- |Aux3=				— optional; General purpose parameter. The meaning is specified by the column header. 	-- |OriginalAirDate=	— optional; This is the date the episode first aired on TV, or is scheduled to air. 	-- |AltDate=			— optional; The next notable air date, such as the first air date of an anime in English. 	-- |Guests=             — optional; List of Guests for talk shows.  Cannot be used simultaneously with Aux1. 	-- |MusicalGuests=      — optional; List of MusicalGuests for talk shows.  Cannot be used simultaneously with Aux2.  	-- |ProdCode=			— optional; The production code in the series. When defined, this parameter also creates a link anchor, 											prefixed by "pc"; for example, List of episodes#pc01. 	-- |Viewers=			— optional; Number of viewers who watched the episode. Should include a reference. 	-- |Aux4=				— optional; General purpose parameter. The meaning is specified by the column header. 	-- |ShortSummary=		— optional; A short 100–200 word plot summary of the episode. 	-- |LineColor=			— optional; Colors the separator line between episode entries. If not defined the color defaults to "#CCCCFF" 											and the article is placed in Category:Episode list using the default LineColor. 											Use of "#", or anything but a valid hex code will result in an invalid syntax. 	-- |TopColor=			— discouraged; Colors the main row of information (that is, not the ShortSummary row). 											Articles using this parameter are placed in Category:Episode lists with row deviations. 	-- |RowColor=			— optional; Switch parameter that must only be defined when the EpisodeNumber= entry is not a regular number 											(e.g. "12–13" for two episodes described in one table entry). 											If the first episode number is even, define pass "on". If the first episode number is odd, pass "off". --]] function p.sublist(frame) 	return main(frame, true) end  --[[ Public function which is used to create an Episode row for an Episode Table used for lists of episodes where all tables are on the same page.
