We are trying to automate the creation of some picture files within an R Script. We have the Excel files looking the way that we want them to, but now need to make a JPG or PNG picture-copy of those excel tables for easier web posting. We've been using the library(xlsx) package for most of our interactions between R and Excel, and it looks like we should be able to send specific java commands through something like ?.jmethods but it's unclear how we would pass as many lines as we need to.

1、安装xlsx: 2、main.js中引入： import XLSX from 'xlsx/dist/xlsx.full.min' 3、要使用的页面引入： import XLSX from "xlsx" 注意（onload事件中this指向会变化，需要在外部把this赋给一个局部变量，然后使用） 文章来源: vue.js中使用js-xlsx读取excel

I have a data frame like this one below and I really want to remove the row names when I export it to a excel file using the xlsx package. bd <- data.frame(id = 1:200, A = c(rep("One", 100), rep("Two", 100)), B = c(rep(1,50), rep(0, 50), rep(1, 50), rep(0, 50))) I have already tried to use the command below, but it keep them in the first column of the excel file. bd <- data.frame(id = 1:200, A = c(rep("One", 100), rep("Two", 100)), B = c(rep(1,50), rep(0, 50), rep(1, 50), rep(0, 50)), row.names=NULL) Is there any way to do this? Set the rownames to NULL to remove them: rownames(bd) <- NULL

I am trying to set a fixed column/cell width to my exported excel files with js-xlsx.
