Tables are basically variables that hold 2 different things, Keys and Values This is an extremely basic explaination but there is so much more to them than what is here ## Keys Keys are identifiers for values, generally keys represent the order of things aka [1] [2] [3] [4] [5] but keys can be strings if needed ["String1"] ["String2"] ["String3"] ## Values Values are any form of data type, even other tables! ## Table Example ```lua table1 = { [1] = "Value", [2] = "Value" } for k,v in pairs(table1) do -- for key and value in pairs, aka if both of them exist in the table table1 do the following print(k .. " " .. v) end returns 1 Value 2 Value ``` ## Usage of table. functions ```lua ⤶ table1 = { "Hello", "My", "Name", "Is",⤶ "Orion"⤶ ⤶ Fruits = { "Apple", "Orange", "Banana", "Pineapple"⤶ }⤶ ⤶ Veggies = {⤶ "Pepper",⤶ "Tomato"⤶ }⤶ ⤶ table.Merge(Fruits, Veggies)⤶ ⤶ print(table.concat(Fruits," "))⤶ ⤶ Pepper Tomato Banana Pineapple⤶ ⤶ ```⤶ ⤶ ```lua⤶ ⤶ Fruits = {⤶ "Apple",⤶ "Orange"⤶ } ⤶ table2 = { "The", "Coolest",⤶ "Person"⤶ ⤶ Veggies = { "Pepper", "Tomato"⤶ } table.Merge(table1, table2) print(table1) ⤶ The⤶ Coolest⤶ Person⤶ Is⤶ Orion⤶ ⤶ ⤶ table.Add(Fruits, Veggies) print(table.concat(Fruits," ")) ⤶ Apple Orange Pepper Tomato⤶ ⤶ ```⤶ ## Usage of "pairs"⤶ ```lua⤶ Names = {"John","Mary","Mark",Den"}⤶ for key,value in pairs(Names) do⤶ print(key.." - "..value)⤶ end⤶ ⤶ 1 - John⤶ 2 - Mary⤶ 3 - Mark⤶ 4 - Den⤶ ```⤶ ## Usage of "ipairs"⤶ ```lua⤶ Names = {[2] = "John", [1] = "Mary",[4] = "Mark",[3] = "Den"}⤶ for key,value in ipairs(Names) do⤶ print(key.." - "..value)⤶ end⤶ ⤶ 1 - Mary⤶ 2 - John⤶ 3 - Den⤶ 4 - Mark⤶ ```⤶ ## Usage of "RandomPairs"⤶ ```lua⤶ Names = {"John","Mary","Mark","Den"}⤶ for key,value in RandomPairs(Names) do⤶ print(value)⤶ end⤶ ⤶ Den⤶ Mary⤶ Mark⤶ John⤶ ```⤶ ## Usage of "SortedPairs"⤶ ```lua⤶ Names = {"John","Mary","Mark","Den"}⤶ for key,value in SortedPairs(Names) do⤶ print(value)⤶ end⤶ ⤶ Den⤶ John⤶ Mark⤶ Mary⤶ ``` ⤶
