可以使用两个嵌套的 for 循环来打印九九乘法表,如下所示:
```python
for i in range(1, 10):
for j in range(1, i+1):
print('{}x{}={}\t'.format(j, i, i*j), end='')
print()
```
输出结果为:
```
1x1=1
1x2=2 2x2=4
1x3=3 2x3=6 3x3=9
1x4=4 2x4=8 3x4=12 4x4=16
1x5=5 2x5=10 3x5=15 4x5=20 5x5=25
1x6=6 2x6=12 3x6=18 4x6=24 5x6=30 6x6=36
1x7=7 2x7=14 3x7=21 4x7=28 5x7=35 6x7=42 7x7=49
1x8=8 2x8=16 3x8=24 4x8=32 5x8=40 6x8=48 7x8=56 8x8=64
1x9=9 2x9=18 3x9=27 4x9=36 5x9=45 6x9=54 7x9=63 8x9=72 9x9=81
```

scala用for循环写九九乘法表,写一个方法,用一个for循环打印九九乘法表
在Scala中,可以使用for循环来打印九九乘法表。下面是一个示例方法,使用一个for循环来打印九九乘法表:
```scala
def printMultiplicationTable(): Unit = {
for (i <- 1 to 9; j <- 1 to i) {
print(s"$j * $i = ${i * j}\t")
if (i == j) println()
}
}
```
这个方法中使用了两个嵌套的for循环,外层循环控制行数,内层循环控制每行的列数。在每次循环中,打印出当前的乘法表达式和结果,并使用制表符进行分隔。当内层循环的变量j等于外层循环的变量i时,换行打印下一行。
调用该方法即可打印出九九乘法表:
```scala
printMultiplicationTable()
```
