You can do something like this

x = [1;0.8;0.5;0.2]
dt = [0.05;0.05; 0.05;0.05]
EL1 = [3; 4; 5; 6 ]
t = table(x,dt,EL1)

There are lots of options for defining a table, the above is a simple example of how to do it. Please type doc table on the command line to see all of the detailed possibilities.

In release R2016b (the release with which this answer was marked) table variable names must be valid MATLAB identifiers, which means neither spaces nor carets (^) are allowed. This restriction was removed in release R2019b so if you want to use those variable names you will need to upgrade to release R2019b or later.
