python，请问9*9乘法表运行后只有第三第四行不对齐是什么原因？

Question

for row in range(1,10):
for column in range(1,row +1):
p = row * column
print(column," × ",row," = ",p,"\t",end = ' ')
print("")

Answer 1

for i in range(1,10):
    for j in range(1,i+1):
        print("{}*{}={:<2}".format(j,i,i*j),end=' ')
    print()

或者：

for i in range(1,10):
    for j in range(1,i+1):
        print(f"{j}*{i}={i*j:<2}",end=' ')
    print()
