数组公式通常称作 CSE (Ctrl+Shift+Enter) 公式，因为不是只按 Enter 键，而是要按 Ctrl+Shift+Enter 完成公式。
数组常量是数组公式的组成部分。可以通过输入一系列项然后手动用大括号 ({ }) 将该系列项括起来创建数组常量。 使用逗号分隔各个项，将创建水平数组（一行）。使用分号分隔项，将创建垂直数组（一列）。要创建二维数组，应在每行中使用逗号分隔项，并使用分号分隔每行。 数组常量中只能包含常量，比如数字、字符串等。 例如：
类似于 setFormula 方法，你可以使用 setArrayFormula 方法来设置数组公式。在 公式输入框 中数组公式会被包含在大括号中({ })。
