Q:

How to make a table from two lists?

I have two lists.
list1 = {115.366, 103.583, 115.24, 91.4648, 93.1291, 485.744, 427.888,489.401, 403.942}

list2 = {114.062, 105.17, 114.857, 91.6497, 93.2112, 398.588, 458.713,410.015, 380.659}

I want these lists to form a table that looks like this. 
115.366    114.062
103.583    105.17
115.24     114.857
and so on

A:

Transpose[{list1, list2}] // TableForm

$\begin{array}{cc}
 115.366 & 114.062 \\
 103.583 & 105.17 \\
 115.24 & 114.857 \\
 91.4648 & 91.6497 \\
 93.1291 & 93.2112 \\
 485.744 & 398.588 \\
 427.888 & 458.713 \\
 489.401 & 410.015 \\
 403.942 & 380.659 \\
\end{array}$

A:

And then there is Grid:
transposedData = Transpose @ { list1, list2 }; (* make a list of tuples *)

Grid[
  transposedData,
  (* options for further formatting go here *)
]

Just to give an idea of what is possible using options for Grid:
Grid[
  transposedData,
  Frame -> {All, None, {{3, 2} -> Directive[Red, Thick]}},
  Alignment -> {Decimal, Decimal}
]

A:

Although solution has been already accepted, here is another way it could be done
Example
Code
Row[(Column[#, Frame -> True] & /@ {list1, list2})]

Note: list1 and list2 as in OP
Output

Reference
Map
Row
Column
