What part is confusing? Try to ask *specific* questions, don't expect us
to do your homework for you.

What is the purpose of these two lines of code?

Why do you single out 7 as a different error?
Why do you treat 2 as an error when it is supposed to be allowed?

The same comments apply for column as for row -- why single out 7, and
why treat 2 as an error?

This will print a single row that looks like:
0 1 2
and so on. Is that the result that you wanted? If not, what result did
you want?

This will print a single row that looks like:
x x x
and so on. Is that the result that you wanted? If not, what result did
you want?

This will print a single row that looks like:
---
Is that the result that you wanted? If not, what result did you want?

Where does table come from? What value or values does it contain?
The question states that you should show the result of i**j (i to the
power of j, e.g. 2**3 = 8, 2**4 = 16, and so forth) but your code
doesn't calculate i**j anywhere.
Have a look at this code, and see if it makes sense to you:
for i in range(3):
print("%4d ::: " % i, end='')
for j in range(3):
print("%d plus %d = %d" % (i, j, i+j), end=' *** ')
print()
Run the code and see what it prints. Can you see what bit of the code is
responsible for what part of the output?
Can you change the code to calculate i**j instead of i+j?
Can you change the code to stop printing the "1 plus 1 =" part of each
cell, and just print the result alone?
Can you change the code to separate the row headers from the cells with
a single | character instead of three : characters?
Can you change the code to use the values entered by the user instead of
a fixed 3 x 3 table?
Are there any other changes you need to make to finish the assignment?
