Create tables in Lua

How would i create a table in lua?

I know how to make one like a = {} but what about in Lua code? something like table.new(tablename)

Thanks!

I actually just found out that i can do

a["x"] = "Test"

then i typed a and it said
{
a = "Test",
}

EDIT: But how would i read it then?

You had previously declared a to be a table, then. You can't simply start placing things into any old variable without declaring it to be a table first. What are you actually trying to do? Including more details will help us clear up whatever might be confusing you, and enable us to better answer your actual question.

This kind of information is easily found in the CC wiki, and on other Lua guides on google.

As Anavirns says, you can google it, these are some basics in Lua, but wanna introduce you:

local tPerson = {} -- Constructs a table
local tPreparedTable = { 1, 4, x = 15, alpha = "80*" }
-- [[
tPreparedTable contains the indexes 1 to 2.
print(tPreparedTable[1]) -- 1
print(tPreparedTable[2]) -- 4
It contains also the indexes x (value: 15) abd alpha (value (string) 80)
]]
tPerson.Anavrins= {} -- Construct in tPersons a table for Anavirns
tPerson.Anavrins.name = "Anavrins"
print(tPerson.Anavirns.name) --> Anavirns
tPerson.Anavrins.name = "is not Anavrins"
for sName, tData in pairs(tPersons) do -- Iterate through every index in tPersons and set sName to the key and tData to the value
  print(sName, tData.Name) --> Anvairns is not Anavirns
end

It just give you a little, very little view of the power of tables.

I know how to make tables, you can just do a = {} but how do i make the code make the table without having to manually go into the code and add it. I want to make a virtual filesystem and i want it to make a table called the file name and when the user writes. It will add that line the user wrote to the table.

I didn't got it. Do you want a function returning a table? Or do you want to save it onto a file?
But if you want virtual filesystems, you can use FSector (API), i coded it exactly for that =)

Variable names should describe data, not be data. Having the name of the file which the user is editing is data and therefore should not be the variable name.

If you really want this then you could use nested tables.

--# your code
openFiles = {}
fileName = "example"
openFiles[fileName] = {}
--# user code
openFiles.example[1] = "this is line 1"
openFiles.example[2] = "this is line 2"

This just looks difficult to use in my opinion.
