How would I add a multidimensional table using a script using table.insert()?

This is not what I want:

Table = {Joe, Fred, Harry}

This is what I want:

Dimension = {{Joe, 1},{Fred, 2},{Harry, 8}}

(Im not doing the real script because I want this to be easy to understand for others :D) How would I do this using a script; For instance - this is creating the normal table:

MyTable = {}
table.insert(MyTable,"Joe")
table.insert(MyTable,"Fred")
table.insert(MyTable,"Harry")

But, I want to make it using table.insert(), because I am making an automatic table maker

Your example would work.

Dimension = {{"Joe", 1},{"Fred", 2},{"Harry", 8}}

If I wanted to print "Joe" then I could simply do

print(Dimension[1][1])
