我处理这个issue。我曾尝试一些CSS解决方案,但我并没有设法解决它。
我最终决定每个小区悬停为了显示行的名称(第一列)和列(标题)。
shinyApp(
ui = fluidPage(
DT::dataTableOutput("mtcarsTable")
),
server = function(input, output) {
output$mtcarsTable <- DT::renderDataTable({
DT::datatable(datasets::mtcars[,1:3],
extensions = c('FixedColumns'), selection=list(mode="single", target="cell"), class = 'cell-border stripe', escape = F ,
options = list(rowCallback = JS(
"function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {",
"var full_text = aData[0] + ','+ aData[1];",
"var headers = Array.prototype.slice.apply(document.querySelectorAll('th'));",
"$('td', nRow).each(function(i) {
this.title = [aData[0], headers[i].innerText].filter(Boolean).join(', ');
});",
"}")
)
)
})
}
)
不幸的是,这似乎是与formatStyle不兼容:
shinyApp(
ui = fluidPage(
DT::dataTableOutput("mtcarsTable")
),
server = function(input, output) {
output$mtcarsTable <- DT::renderDataTable({
DT::datatable(datasets::mtcars[,1:3],
extensions = c('FixedColumns'), selection=list(mode="single", target="cell"), class = 'cell-border stripe', escape = F ,
options = list(rowCallback = JS(
"function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {",
"var full_text = aData[0] + ','+ aData[1];",
"var headers = Array.prototype.slice.apply(document.querySelectorAll('th'));",
"$('td', nRow).each(function(i) {
this.title = [aData[0], headers[i].innerText].filter(Boolean).join(', ');
});",
"}")
)
) %>%
formatStyle(columns = 1, backgroundColor = styleInterval(c(19,20,22), c('red','green','yellow', 'black')))
})
}
)
当我执行额外的步骤,我没有得到一个错误,也没有渲染的数据表。
我在寻找之一:能够混合rowCalllback和Styleinterval或一般,更好的解决方案,让用户知道不正是他在一个大的数据表。
先感谢您。
我会做这样的提示:
library(DT)
datatable(head(iris),
options=list(initComplete = JS(c(
"function(settings){",
" var table = settings.oInstance.api();",
" var ncols = table.columns().count();",
" var nrows = table.rows().count();",
" for(var i=0; i<nrows; i++){",
" var rowname = table.cell(i,0).data();",
" for(var j=1; j<ncols; j++){",
" var headerName = table.column(j).header().innerText;",
" var cell = table.cell(i,j);",
" cell.node().setAttribute('title', rowname + ', ' + headerName);",
" }",
" }",
"}")))
)
