__NOTOC__
This function sorts tables by index numerically from largest to smallest or from smallest to largest.
Its also useful for removing gaps from your table.

'''Important : WORKS ONLY FOR TABLES WITH NUMERIC INDEXES!'''
<br>

==Syntax==
<syntaxhighlight lang="lua">table table.sortNumerically( table theTable, bool fromHighestToLowest = false )</syntaxhighlight>

===Required Arguments===
* '''theTable''': the table you would like to sort.
===Optional Arguments===
* '''fromHighestToLowest''': a bool representing whether the table is to be sorted by index from highest to lowest or lowest to highest.
===Returns===
Returns sorted table.

==Code==
<syntaxhighlight lang="lua">
function table.sortNumerically(theTable, fromHighestToLowest)
local sortTable = { }
for k, v in pairs(theTable) do
table.insert(sortTable, {k, v})
end

table.sort(sortTable, function(a,b)
local result = a[1]<b[1]
if fromHighestToLowest then
result = a[1]>b[1]
end
return result
end)

theTable = {}

for k,v in ipairs(sortTable) do
table.insert(theTable, v[2])
end
return theTable
end
</syntaxhighlight>

==Example==
The code below will print the table in the correct sorted order.
<syntaxhighlight lang="lua">
local theTable = {[3] = "Dino", [1] = "Doll", [2] = "Car",[6] = "Rattle", [4] = "Dog", [5] = "Boat"}
local theTable2 = {[3] = "Dino", [1] = "Doll", [9] = "Rattle", [4] = "Dog"}

local sortedTable = table.sortNumerically(theTable, true)
iprint(sortedTable) -- {"Rattle", "Boat", "Dog", "Dino", "Car", "Doll"}

local sortedTable2 = table.sortNumerically(theTable, false)
iprint(sortedTable2) -- {"Doll", "Car", "Dino", "Dog", "Boat", "Rattle"}

local sortedTable3 = table.sortNumerically(theTable2, false)
iprint(sortedTable3) -- {"Doll", "Dino", "Dog", "Rattle"}
</syntaxhighlight>
