RANDARRAY函数返回一个随机数数组。用户可以指定要填充的行和列的数量，最小值和最大值，以及返回整数或十进制值。
参数
必需
描述
[rows]
否
要返回数据的行数
[columns]
否
要返回数据的列数
[min]
否
随机数的最小值
[max]
否
随机数的最大值
[whole_number]
否
返回整数或浮点数：整数则为true，浮点数为false。
注意:
RANDARRAY 函数仅在allowDynamicArray为true时有效。
RANDARRAY 函数将返回一个数组，如果该数组是公式的最终结果，则将溢出。
如果没有行或列参数，RANDARRAY将返回0到1之间的一个值。
如果不提供最小值或最大值参数，则RANDARRAY将分别默认为0和1。
参数最小值必须小于最大值，否则RANDARRAY将返回#VALUE！错误。
如果不输入Whole_number参数，则RANDARRY将默认为FALSE，即浮点数。
