+Some WikiText is recognised only while the parser is in block mode.
+
+Common characteristics of such block mode WikiText:

+* The closing punctuation must come at the end of the line (in some cases the end of the line //is// the closing punctuation.
+
+|!~WikiText|!Punctuation|
+|[[Block Quotes in WikiText]] |Multi-line block quotes are enclosed by lines containing only the text `<<<`; single line block quotes are also possible.|

+|[[Lists in WikiText]]|Each list item is on its own line.|
+|[[Paragraphs in WikiText]]|Any text other than the start punctuation of one of the other block mode WikiText will start a paragraph.

+|[[Tables in WikiText]]|Each table row is a line starting and ending with `|`.|
+|[[Typed Blocks in WikiText]]|Enclosed by lines starting with `$$`.|
+
+The above WikiText types are only recognised in ''block mode''. However, the text <<.em enclosed>> by most of them will be parsed in ''inline mode'' ([[Block Quotes in WikiText]] and [[Styles and Classes in WikiText]] are the two exceptions in which the parser will continue in ''block mode''). While in ''inline mode'' the parser may encounter something which moves it to ''block mode'' (see [[WikiText parser mode transitions]]).

+At the end of the terminating line, the parser will return to ''block mode''. 
+<<.tip 'Note: [[Hard Linebreaks in WikiText]] require an extra blank line after the trailing `"""` before the parser will return to <b>block mode</b>'>>.

+If the punctuation for the above types of WikiText is encountered while the parser is in ''inline mode'', it will be //ignored// and output as-is.

+
+!! Start mode
+
+By default the parser starts in [[block mode|Block Mode WikiText]]. However, a tiddler can instead be transcluded with [[inline mode|Inline Mode WikiText]] in which case [[block mode WikiText|Block Mode WikiText]] will not be recognised.
+
+At the start of text only, the parser will also recognise any [[pragma mode WikiText|Pragma]].
+
+!! Transitions from pragma mode
+
+At the start of text, the parser will recognise any [[pragma|Pragma]]. If none are found then it will move to [[inline|Inline Mode WikiText]] or [[block|Block Mode WikiText]] mode depending on the transclusion mode. If any [[pragma|Pragma]] are found then it will continue looking for [[pragma|Pragma]] until it finds one or more blank lines not followed by the start of a new pragma.
+
+!! Transitions from block mode
+
+When the parser encounters most [[block mode|Block Mode WikiText]] start punctuation it transitions to [[inline mode|Inline Mode WikiText]]. This means
+he text enclosed by most [[block mode|Block Mode WikiText]] constructs will be parsed using [[inline mode|Inline Mode WikiText]].
+
+<<.tip """The start "punctuation" for a paragraph is "invisible". Even for paragraphs the parser moves to [[inline mode|Inline Mode WikiText]]""">>
+
+However, there are a few constructs whose enclosed text is parsed using [[block mode|Block Mode WikiText]]:
+
+* [[Multi-line block quotes|Block Quotes in WikiText]]
+* [[Multi-line style blocks|Styles and Classes in WikiText]]
+* [[Typed blocks|Typed Blocks in WikiText]]
+
+When the start punctuation for these are encountered, the enclosed text will continue to be parsed in [[block mode|Block Mode WikiText]].
+
+[[Horizontal rules|Horizontal Rules in WikiText]] are another special case. They do not enclose any text, so there is no opportunity for the parser to transition to [[inline mode|Inline Mode WikiText]].
+
+Opening [[widget|Widgets in WikiText]] or [[HTML|HTML in WikiText]] tags provide another way the parser can transition. When such a tag is <<.em not>> followed by a blank line, then the contents enclosed by the tag will be parsed in [[inline mode|Inline Mode WikiText]]. See the [[HTML examples|WikiText parser mode: HTML examples]].
+
+!! Transitions from inline mode
+
+* The parser will move back to [[block mode|Block Mode WikiText]] after the end of a line which terminates [[block mode|Block Mode WikiText]] ~WikiText. In other words, when the block mode close punctuation is encountered.
+* When the opening [[widget|Widgets in WikiText]] or [[HTML|HTML in WikiText]] tag is followed by a blank line, then the contents enclosed by the tag will be parsed in [[block mode|Block Mode WikiText]]. See the [[HTML examples|WikiText parser mode: HTML examples]].
+* Transcluded text and text pulled in via a macro call can transition the parser away from [[inline mode|Inline Mode WikiText]]. See [[transclusion examples|WikiText parser mode: transclusion examples]] and [[macro examples|WikiText parser mode: macro examples]] for more details.

+The list syntax is recognised in [[block mode|Block Mode WikiText]] and the enclosed contents are parsed using [[inline mode|Inline Mode WikiText]].

The contents of the macro contains table syntax which is only recognised in [[block mode|Block Mode WikiText]]. 
+
+Therefore, in #1 above the table syntax is not recognised. In #2 above, the blank line after the open `div` tag moves the parser back into [[block mode|Block Mode WikiText]], the macro call inherits it and the table is recognised.
+
+When calling macros using the [[widget|MacroCallWidget]], the parse mode will be inline (#3 and #4 above) unless it is written as an open tag with a following blank line (#5 above).

+Given the tiddler  [[table-example]] defined with these contents:
+<$codeblock code={{table-example}}/>
+then
+<table><<wikitext-example-table-header>><tbody>
+<<wikitext-example-table-row 1 "* {{table-example}}">>
+<<wikitext-example-table-row 2 """* <div>
+
+{{table-example}}
+</div>
+""">>

+<<wikitext-example-table-row 4 "* <$transclude tiddler=table-example></$transclude>">>
+<<wikitext-example-table-row 5 """* <$transclude tiddler=table-example>
+
+</$transclude>""">>
+<<wikitext-example-table-row  6 "* <$transclude tiddler=table-example mode=block/>">>
+</tbody></table>
+
+The list syntax is recognised in [[block mode|Block Mode WikiText]] and the enclosed contents are parsed using [[inline mode|Inline Mode WikiText]]. When the parser encounters a [[wikitext transclusion|Transclusion in WikiText]] it will use the current parse mode to parse the contents of the transcluded tiddler. The contents of the example tiddler contains table syntax which is only recognised in [[block mode|Block Mode WikiText]]. 
+
+Therefore, in #1 above the table syntax is not recognised. In #2 above, the blank line after the open `div` tag moves the parser back into [[block mode|Block Mode WikiText]], the transcluded text inherits it and the table is recognised.
+
+When transcluding tiddlers using the [[widget|TranscludeWidget]], the parse mode will be inline (#3 and #4 above) unless it is written as an open tag with a following blank line (#5 above).
+
+<<.tip "See also [[WikiText parser mode: macro examples]] for similar examples. The only difference here is <<.wlink TranscludeWidget>> has a <<.attr mode>> attribute (extra example #6) which allows the parse mode to be explicitly overridden rather than come implicitly based on the they way the tag is written">>
+
+---
+
+In these examples, the transclusions are at the top level instead of enclosed in list items:
+
+<table><<wikitext-example-table-header>><tbody>
+<<wikitext-example-table-row 1 "{{table-example}}">>
+<<wikitext-example-table-row 2 """<div>
+
+{{table-example}}
+</div>
+""">>
+<<wikitext-example-table-row 3 "<$transclude tiddler=table-example/>">>
+<<wikitext-example-table-row 4 "<$transclude tiddler=table-example></$transclude>">>
+<<wikitext-example-table-row 5 """<$transclude tiddler=table-example>
+
+</$transclude>""">>
+<<wikitext-example-table-row  6 "<$transclude tiddler=table-example mode=inline/>">>
+</tbody></table>
+
+
+Of these examples, only the two <<.wlink TranscludeWidget>> tags which are not followed by a blank line and the widget call using <<.attr mode>>=<<.value inline>> are parsed using [[inline mode|Inline Mode WikiText]].
