I've been scripting for a while now, and I've never learned how to use tables. I really want to learn how to use tables, but I find the wiki article on them to be hard to understand. How do I go about learning how to use them? And what are some ways I could include tables in my own scripts?

How do I get better at using tables?

A table is a list. This list can contain absolutely anything. To create it, we just use a regular variable name, followed by curly brackets.
local t = {}
Now we just put anything we want inside of those brackets - separated by commas.
local t = {"Hello, world!", workspace.Part, true}
Notice how we can put all types of values in the table.
We can add values, remove values, etc. with table manipulation functions.
To access a value from a table, we need to use something called a key. The key is what you use to get the value. For simple lists, the keys are numbers:
local t = {"Hello, world!", --Key: 1
workspace.Part, --Key: 2
true} --Key: 3
To use a key, we put brackets after the table's name, followed by the key. This gives us the value corresponding to the given key.
print( t[1] )
--> Hello, world!
There's also ways where we can edit what key corresponds with what value. This video covers it pretty well.

Thanks for clearing some things up! But what would be an example of where I would use this though? I really want to implement this into my scripting but I have no idea when I would use it and what situations it would be for.
That's where creativity comes in. You can use tables for all sorts of things. You could make a list of admins, or vips. Or maybe a list of maps. You could also make a list of all players still alive, or all the dead ones. There's also methods that return tables -- like GetChildren, which is very useful. The better you are a table manipulation, the more useful they become.
