    5 Wiki markup is a core feature in Trac, tightly integrating all the other parts of Trac into a flexible and powerful whole.
    6 
    7 Trac has a built-in small and powerful wiki rendering engine. This wiki engine implements a growing subset of the commands from other popular Wikis, especially [http://moinmo.in/ MoinMoin] and [trac:WikiCreole].
    8 
    9 This page will give you an in-depth explanation of the wiki markup available anywhere WikiFormatting is allowed.
    10 
    11 The sections below provide an overview for the most common syntax, each link in the ''Category'' column will lead you to the more detailed explanation later in this page.
    12 
    13 A few other wiki pages present the advanced features of the Trac wiki markup in more depth:
    14  - TracLinks covers all the possible ways to refer precisely to any Trac resource or parts thereof.

    288  * all the font styles marks have to be used in opening/closing pairs, 
    289    and they must nest properly; in particular, an `''` italic can't be paired

    292284== Headings
    293285
    294 You can create heading by starting a line with one up to six ''equal'' characters ("=") followed by a single space and the headline text.

    295287
    296288[=#hn]
    297 The headline text can be followed by the same number of "=" characters, but this is not mandatory. That is, `=== Section3 ===` is identical to `=== Section3`.

    504 Cell headings can be specified by wrapping the content in a pair of '=' characters.

    562 If contrary to the example above, the cells in your table contain more text, it might be convenient to spread a table row over multiple lines of markup. The `\` character placed at the end of a line after a cell separator tells Trac to not start a new row for the cells on the next line.
