Add Variables Concatenated from Another Table
Add variables to the table T by horizontally concatenating it with T2.
T = [T T2];
Display the first five rows of T.

The table T now has 7 variables and 100 rows.
If the tables that you are horizontally concatenating have row names, horzcat concatenates the
tables by matching the row names. Therefore, the tables must use the same row names, but the row
order does not matter.
Add Variable from Workspace to Table
Add the names of patients from the workspace variable LastName before the first table variable in T.
You can specify any location in the table using the name of a variable near the new location. Use
quotation marks to refer to the names of table variables. However, do not use quotation marks for
input arguments that are workspace variables.
T = addvars(T,LastName,'Before','Age');
head(T,5)

You also can specify locations in a table using numbers. For example, the equivalent syntax using a
number to specify location is T = addvars(T,LastName,'Before',1).
