如何在DT表中显示小数秒

Question

我想在DT数据表中看到毫秒：

options(digits.secs=6)
library(data.table)
d = data.table(x = 1:10,time = as.POSIXct('2015-03-23 12:00:00.123'))
library(DT)
datatable(d)

Answer 1

options(digits.secs=6)
library(data.table)
d = data.table(x = 1:10,time = as.POSIXct('2015-03-23 12:00:00.123'))
d$time = strftime(d$time,'%Y-%m-%d %H:%M:%OS3')

View(d)
library(DT)
datatable(d)

给出：
