在 DT 表中的一行中嵌入闪亮的小部件

【中文标题】在 DT 表中的一行中嵌入闪亮的小部件【英文标题】：Embed Shiny widgets in a row in a DT table 【发布时间】：2022-01-12 16:08:03 【问题描述】：我想在 DT 表的一行中直接嵌入 sliderInput() 小部件。
我的问题与此不同：Shiny widgets in DT Table，因为它使用现有的数据框（不完全基于用户输入）。
所需的表格（见下图）显示了一个综合指数（“指数”栏，第 4 栏），该指数根据某些指标（例如失业率）反映了几个国家青年的劳动力市场状况。指标分为四个维度。按维度划分的（子）索引值显示在第 6-9 列中。 左侧面板中的四个滑块输入（）允许为四个维度中的每一个赋予不同的权重（“0”表示静音，“3”表示最高权重）。更改 sliderInput() 会触发聚合索引的重新计算，相应的“加权索引”的结果显示在第 5 列中。
为了更直观地向用户显示 sliderInput() 属于哪个列，我想将它们直接放在相应列的表中（例如，第 6 列中维度“Activity State”的 sliderInput()）标题下方的一行。我在下面的.png 中将这些地方标记为红色。因此，使用 selectInput 小部件可能会更好）。
如果有人能给我提示如何实现这一点，我将不胜感激？
表格的表头是使用 htmltools 包创建的（参见下面的代码），这可能会使事情复杂化。
请注意，除了 ui 和服务器部分之外，下面的代码还包含我的数据框的一个最小示例和一个根据用户输入重新计算索引的辅助函数。

【问题讨论】：
【参考方案1】：这是使用selectInput 的解决方案。我们可以将输入包装在div 中并使用escape = FALSE 参数 - 并在drawCallback 中添加Shiny.bindAll。
此外，我正在使用dataTableProxy 和replaceData 来更新表格，否则您将遇到here 描述的问题。

【讨论】：
非常感谢，@ismirsehregal。你的回答很有帮助！两个小的后续问题：i）你知道我如何将选择权重下拉菜单置于“标题”列（例如“活动状态”）下方吗？ ii) 你知道是否有一种简单的方法来连接单词（例如将长单词分成较小的部分）。解决方案是在“sketch @jmk 抱歉，我不知道如何使下拉选项居中 - 也许您可以将其放在单独的问题中。关于换行符，您可以再次将标签包装在 div 中并使用例如div("Select weight of Dimension Working Conditions:", style = "line-break: loose;")。请参阅this 了解更多信息。以上是关于在 DT 表中的一行中嵌入闪亮的小部件的主要内容，如果未能解决你的问题，请参考以下文章
