如何将两个for循环的输出组合成一个“表”格式？

result = []
for i in range(1, 4):
    for j in range(1, 4):
        result.append([i, j])

# 输出结果
for item in result:
    print(item)

[1, 1]
[1, 2]
[1, 3]
[2, 1]
[2, 2]
[2, 3]
[3, 1]
[3, 2]
[3, 3]

result = []
for i in range(1, 4):
    for j in range(1, 4):
        result.append({'Column1': i, 'Column2': j})

# 输出结果
for item in result:
    print(item)

{'Column1': 1, 'Column2': 1}
{'Column1': 1, 'Column2': 2}
{'Column1': 1, 'Column2': 3}
{'Column1': 2, 'Column2': 1}
{'Column1': 2, 'Column2': 2}
{'Column1': 2, 'Column2': 3}
{'Column1': 3, 'Column2': 1}
{'Column1': 3, 'Column2': 2}
{'Column1': 3, 'Column2': 3}
