In Lua, "table" is a fundamental type that can be used either as an array (numerical index, fast) or as an associative array. The keys and values can be of any type, except nil. The following focuses on non-numerical indexes. A table literal is written as { value, key = value, [index] = value, ["non id string"] = value }. For example:
See Help:Sortable tables#Numerical sorting problems and meta:Help:Sorting#Sort modes Equal rank If you simply code as the second parameter an indicator that two items are equally ranked, e.g. "4=", the template interpreter will treat this as an additional parameter (i.e. parameter 4, which it will then not use).
They are associative arrays with addition of automatic numeric key and special syntax. A table is a set of key and data pairs, where the data is referenced by key; in other words, it is a hashed heterogeneous associative array. Tables are created using the {} constructor syntax.
The basic idea behind a hash table is that accessing an element of an array via its index is a simple, constant-time operation. Therefore, the average overhead of an operation for a hash table is only the computation of the key's hash, combined with accessing the corresponding bucket within the array.
The module itself must return a Lua table of values. A Lua table is expressed as a list of values separated by commas, within curly braces. When the module is called by #invoke, the function it names (the first argument after |) is looked for in that table. That function, in turn, is expected to return something that can be represented as a string.
Table sort keys are best defined using the data-sort-value attribute, like so: | data-sort-value="Doe, John" | John Doe. Please see Help:Sortable tables § Specifying a sort key for a cell for details.
As a result, multi-key sorting (sorting by primary, secondary, tertiary keys, etc.) can be achieved by sorting the least significant key first and the most significant key last. For example, to sort the table by the "Text" column and then by the "Numbers" column, you would first click on and sort by the "Numbers" column, the secondary key, and ...
Luanti (Formally Minetest) uses Lua for in-game programming of robots, microcontrollers and sorting tubes, using popular addons. Moho , an animation software package distributed by Smith Micro Software , uses Lua as its scripting language, and all of its native tools are built as editable scripts.
