    33Processors are WikiMacros designed to provide alternative markup formats for the [TracWiki Wiki engine]. Processors can be thought of as ''macro functions to process user-edited text''.  
    44 
    5 Wiki processors can be used in any Wiki text throughout Trac, 
    6 for various different purposes, like: 
    7  - [#CodeHighlightingSupport syntax highlighting] or for rendering text verbatim, 
    8  - rendering [#HTMLrelated Wiki markup inside a context],  
    9    like inside <div> blocks or <span> or within <td> or <th> table cells, 
    10  - using an alternative markup syntax, like [wiki:WikiHtml raw HTML] and 
    11    [wiki:WikiRestructuredText Restructured Text], 
    12    or [http://www.textism.com/tools/textile/ textile]

    17 To use a processor on a block of text, first delimit the lines using

    26 Immediately after the `{{{` or on the line just below,  
    27 add `#!` followed by the ''processor name''.

    3730This is the "shebang" notation, familiar to most UNIX users.

    39 Besides their content, some Wiki processors can also accept ''parameters'', 
    40 which are then given as `key=value` pairs after the processor name,  
    41 on the same line. If `value` has to contain space, as it's often the case for 
    42 the style parameter, a quoted string can be used (`key="value with space"`). 
    43  
    44 As some processors are meant to process Wiki markup, it's quite possible to 
    45 ''nest'' processor blocks. 
    46 You may want to indent the content of nested blocks for increased clarity, 
    47 this extra indentation will be ignored when processing the content.

    154142The following processors are included in the Trac distribution: 
    155143 
    156144|| '''`#!default`''' || Present the text verbatim in a preformatted text block. This is the same as specifying ''no'' processor name (and no `#!`) || 
    157 || '''`#!comment`''' || Do not process the text in this section (i.e. contents exist only in the plain text - not in the rendered page). || 
    158 |||| || 
    159 ||||= '''HTML related''' =|| 
     145|| '''`#!comment`''' || Do not process the text in this section, i.e. contents exist only in the plain text - not in the rendered page. || 
     146|| '''`#!rtl`''' || Introduce a Right-To-Left block with appropriate CSS direction and styling ''(since 0.12.2)'' || 
     147|||| || 
     148||||= '''[=#HTMLrelated HTML related]''' =|| 
    160149|| '''`#!html`''' || Insert custom HTML in a wiki page. || 
    161150|| '''`#!htmlcomment`''' || Insert an HTML comment in a wiki page (''since 0.12''). || 
     
    165154|| '''`#!td`''' || Wrap an arbitrary Wiki content inside a <td> element (''since 0.12'') || 
    166155|| '''`#!th`''' || Wrap an arbitrary Wiki content inside a <th> element (''since 0.12'') || 
    167 || '''`#!tr`''' || Can optionally be used for wrapping `#!td` and `#!th` blocks, either for specifying row attributes of better visual grouping (''since 0.12'') || 
     156|| '''`#!tr`''' || Can optionally be used for wrapping `#!td` and `#!th` blocks, either for specifying row attributes or better visual grouping (''since 0.12'') || 
     157|| '''`#!table`''' || Can optionally be used for wrapping `#!tr`, `#!td` and `#!th` blocks, for specifying table attributes. One current limitation however is that tables cannot be nested. (''since 0.12'') ||  
    168158|| || See WikiHtml for example usage and more details about these processors. || 
    169159|||| || 
     
    172162|| '''`#!textile`''' || Supported if [http://cheeseshop.python.org/pypi/textile Textile] is installed. See [http://www.textism.com/tools/textile/ a Textile reference]. ||

    249 In fact they work the same way, only the usage syntax differs.
