Editing WoW:Lua functions (section)

=== Table ===
These table functions are shorthand references to the Lua table library (which is available via "table.", see [http://lua-users.org/wiki/TableLibraryTutorial TableLibraryTutorial] for more info).

Be also aware that many table functions are designed to work with tables indexed only with numerical indexes, starting with 1 and without holes (like {[1] = "foo", [3] = "bar"} --- recognize that [2] will be nil in this table). When working with any other tables behavior is not defined and might lead to unexpected results. Not being aware of this fact is one major causes for bugs in code written in Lua.

: [[API foreach|foreach]](table,function) - Execute function for each element in table. (deprecated, used pairs instead)
: [[API foreachi|foreachi]](table,function) - Execute function for each element in table, indices are visited in sequential order. (deprecated, used ipairs instead)
: [[API getn|getn]](table) - Return the size of the table when seen as a list. This is deprecated, it is replaced by the # operator. Instead of table.getn(table), use #(table).
: [[API ipairs|ipairs]](table) - Returns an iterator of type integer to traverse a table.
: [[API pairs|pairs]](table) - Returns an iterator to traverse a table.
: [[API sort|sort]](table[, comp]) - Sort the elements in the table in-place, optionally using a custom comparator.
: {{api|tContains}}(table, value) - returns true if value is contained within table. This is not standard Lua, but added by Blizzard.
: [[API tinsert|tinsert]](table[, pos], value) - Insert value into the table at position pos (defaults to end of table)
: [[API tremove|tremove]](table[, pos]) - Remove and return the table element at position pos (defaults to last entry in table)
: [[API wipe|wipe]](table) - Restore the table to its initial value (like tab = {} without the garbage). This is not standard Lua, but added by Blizzard.
