Question

我用一个自定义容器构建了一个<a href="/" onclick="event.preventDefault()">here</a>表，类似于一个here（第2.6-2.6个自定义表容器）。我正在打包使用该表的闪亮应用程序，我想找出用于定义DT对象的哪些软件包th()，tr()和thead() ，属于..？

sketch等。为我指出了各种??thead函数，但是DT没有返回任何文档。感谢您的指导！

Answer 1

您应该注意，在草图的定义中，它们称为iris %>% group_by(Species) %>% summarise_if(.predicate = is.numeric, .funs = ~ list(summary(object = .))) %>% unnest() %>% group_by(Species) %>% mutate(Statistic = names(x = summary(object = rnorm(n = 1)))) %>% ungroup() %>% select(Species, Statistic, everything())，这很简单

htmltools::withTags

要注意的是它将使用替代和function (code) { eval(substitute(code), envir = as.list(tags), enclos = parent.frame()) } <bytecode: 0x000001c832d09200> <environment: namespace:htmltools>。如果我们看一下envir = as.list(tags)，它是带有以下命名对象/函数的列表：

tags

其中的每一个都具有基本相同的形式：

> names(tags)
  [1] "a"           "abbr"        "address"     "area"        "article"     "aside"       "audio"      
  [8] "b"           "base"        "bdi"         "bdo"         "blockquote"  "body"        "br"         
 [15] "button"      "canvas"      "caption"     "cite"        "code"        "col"         "colgroup"   
 [22] "command"     "data"        "datalist"    "dd"          "del"         "details"     "dfn"        
 [29] "div"         "dl"          "dt"          "em"          "embed"       "eventsource" "fieldset"   
 [36] "figcaption"  "figure"      "footer"      "form"        "h1"          "h2"          "h3"         
 [43] "h4"          "h5"          "h6"          "head"        "header"      "hgroup"      "hr"         
 [50] "html"        "i"           "iframe"      "img"         "input"       "ins"         "kbd"        
 [57] "keygen"      "label"       "legend"      "li"          "link"        "mark"        "map"        
 [64] "menu"        "meta"        "meter"       "nav"         "noscript"    "object"      "ol"         
 [71] "optgroup"    "option"      "output"      "p"           "param"       "pre"         "progress"   
 [78] "q"           "ruby"        "rp"          "rt"          "s"           "samp"        "script"     
 [85] "section"     "select"      "small"       "source"      "span"        "strong"      "style"      
 [92] "sub"         "summary"     "sup"         "table"       "tbody"       "td"          "textarea"   
 [99] "tfoot"       "th"          "thead"       "time"        "title"       "tr"          "track"      
[106] "u"           "ul"          "var"         "video"       "wbr"

因此，从根本上讲，这只是一种使用指定标记调用> tags$thead function (...) tag("thead", list(...)) <bytecode: 0x000001c82c4a2678> <environment: namespace:htmltools>函数的简便方法。直接调用示例：

tag

R：tr（），th（）和thead（）-它们属于哪个包？
