Javascript 替换可编辑数据表中的初始数据帧，并在另一个表中使用该新数据帧
我的闪亮应用程序中有一个嵌套的数据表。子表中的某些列可由用户编辑。这里的目标是让用户编辑这些值，然后用这些新值替换数据框。然后，我想将替换后的数据帧用于另一个表。我需要在另一个表中使用编辑后的值进行计算 工作流：Javascript 替换可编辑数据表中的初始数据帧，并在另一个表中使用该新数据帧,javascript,r,shiny,datatables,dt,Javascript,R,Shiny,Datatables,Dt,我的闪亮应用程序中有一个嵌套的数据表。子表中的某些列可由用户编辑。这里的目标是让用户编辑这些值，然后用这些新值替换数据框。然后，我想将替换后的数据帧用于另一个表。我需要在另一个表中使用编辑后的值进行计算 工作流： create nested data table -> user edits values -> initial data is replaced by new data -> use the new data for another table 我曾尝试使用rea

- 在

library（jsonlite）
寄存器处理器(
“嵌套数据”，
功能（数据，…）{
fromJSON（toJSON（数据））
},
力=真
)
- 然后可在

观察({
打印（输入[[“数据”]]）
})
第二轮 正如我在评论中所说，最好在
渲染toFixednumber库（DT）
df_children首先，我很抱歉没有添加可重复工作的代码，这段代码是最新的。然而，我知道你在这里做什么<代码>输入[[“数据”]嵌套数据的输出。我需要做的就是抓住它，按照我喜欢的格式编排。再次感谢你，你真厉害@TimothyMcwilliams的一个问题是，编辑时某些单元格值会转换为字符。这是由于.toFixed（2）
引起的。而且，这使结果更加接近。最好使用render
选项仅显示舍入值，而不在内部舍入。啊，好吧，我不知道使用。toFixed（2）
将数据转换为字符。我将给渲染看一看。我假设我只需要用render（）
@TimothyMcwilliams-No来包装这一行，而不是以这种方式工作。看我的编辑（第二轮）。明白了，和我想的完全不同。谢谢你的编辑。对于子表，所有这些似乎都按预期工作。但是，list（render=render_js，targets=colIdx+1+1:4）
在应用时会破坏整个表<代码>目标
索引列1到4是否正确？
