How do I convert this to precise columns and rows?

Question

having a hard time converting to neat columns and rows. Can anyone help?

I have been trying to set columns and rows to 0 and work from there but I cant figure it out. I just dont know where to insert the information.

n = 5

rate = 0.05

for n in range(0, 3):

principal = 10000

for n in range (0,6):

    principal <= 15000

    simple = principal *  (1 + rate * n)

    compound = principal * (1 + rate)**n

    ratea = rate * 100

    ratea = int(ratea)

    principal = int(principal)

    print((ratea),"% $",principal," $","{:.2f}".format(simple)," $","{:.2f}".format(compound))

    principal = principal + 1000

rate = rate + 0.05

Use the string method format.
