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:
A table is a sequence, optionally supplemented by named keys: digit["two"]="2". Several table functions like table.concat will only work with the numbered values and ignore named keys. The metatable offers a large, optional set of methods for altering table behavior. For example, you can define a table to be callable like a function.
This module includes a number of set operations for Lua tables. It currently has union, intersection and complement functions for both key/value pairs and for values only. . It is a meta-module, meant to be called from other Lua modules, and should not be called directly from #invo
Values are decimal representations of UTF-8 codes. The table is organized as a table of tables because the Lua pairs keyword returns table data in an arbitrary order. Here, we want to process the table from top to bottom because the entries at the top of the table are also found in the ranges specified by the entries at the bottom of the table.

Lua provides functions to push and pop most simple C data types (integers, floats, etc.) to and from the stack, and functions to manipulate tables through the stack. The Lua stack is somewhat different from a traditional stack; the stack can be indexed directly, for example. Negative indices indicate offsets from the top of the stack. For ...
This help-page, Help:Lua debugging, explains issues of writing Lua script and debugging the source code, to remove errors or improve performance. Because Lua is a "semi-compiled" interpreted language, it does not prescreen for all common syntax errors, nor detect misspelled variables, which are only found at runtime when seeing the " Script ...
