在格式提示中，有三个步骤。
获取格式
从引用的单元格中获取格式
从百分比值中获取百分比格式
从特殊函数中获取格式，例如：NOW/TODAY/IRR/NPV
从动态引用中获取格式，例如：=INDIRECT("C3")
格式计算
以下是一些格式计算策略的列表：
日期格式减去日期格式将是空格式
日期格式加上时间格式将是日期时间格式
货币格式乘以数字格式将是货币格式
数字格式乘以百分比格式将是数字格式
空格式加上百分比格式将是空格式
SUM/MAX/MIN/AVEDEV/LOOR/ROUND/ROUNDUP/ROUNDDOWN/INT/TRUNC函数将在第一个参数的第一个单元格使用格式。
适用格式
当输入公式到单元格时，如果单元格没有明确设置格式，SpreadJS将应用格式提示到该单元格。
你可以使用spread.options.formulaFormatHint选项来控制是否启用格式提示。
