Adding colors to column values messes up the spacing

[GoogleCodeExporter]

What steps will reproduce the problem?

#!/usr/bin/python
from prettytable import PrettyTable

x = PrettyTable(["City name", "Area", "Population", "Annual Rainfall"])
x.align["City name"] = "l" # Left align city names
x.padding_width = 1 # One space between column edges and contents (default)
x.add_row(["Adelaide",1295, 1158259, 600.5])
x.add_row(["Brisbane",5905, 1857594, "\033[94m1146.4\033[0m"])
x.add_row(["Darwin", 112, 120900, 1714.7])
x.add_row(["Hobart", 1357, 205556, 619.5])
x.add_row(["Sydney", 2058, 4336374, 1214.8])
x.add_row(["Melbourne", 1566, 3806092, 646.9])
x.add_row(["Perth", 5386, 1554769, 869.4])
print x

What is the expected output? What do you see instead?

I would expect similar spacing and formatting with colors.

What version of the product are you using? On what operating system?

latest

The problem is related to the TERM environment variable. When TERM=xterm, the 
problem exists. When TERM=xterm-color, the problem is resolved.
