[英]How to use ColVis plugin in DT to hide multiple columns in a custom container?
[英]Single/multiple conditions for columns formating with DT
這與這個問題有關。Shiny中是否有類似的方法可以對excel中的多列進行條件格式設置,提供的解決方案效果很好,但是我在如何擴展代碼以滿足新要求方面有些棧。 因此,如果我具有以下數據框,並希望根據以下條件更改五列的背景色:
否則X =“”或Y =“”則X,Y的顏色為白色
對於A,B,C列
我試圖在此處擴展提供的解決方案,但是沒有用。 誰能幫助您解決這個問題。
output$contents <- renderDataTable({
df <- data.frame(
id = 1:10,
X = c(-2, 4, 40, -0.1228, 2.9, 9, 2.7, 2.7, 31, -30),
Y = c(-18.9, -19.5, 19.6, 12, 11.1, 73, 4.3, 39, 2.5, 1.6),
A = c(-7.3, 5.1 ,0.12, 15, 21, 1.2, -0,07, 4.3, 39, 2.5)
B = c(-18.9, 0.12, 15, 11.1, 73, -2, 4, 40, -19.5, 19.6)
C = c(4.3, 39, 2.5, 1.6, -7.3, 6, 5.1 ,0.12, -0.07, 4.3)
library(DT)
datatable(df) %>% formatStyle(
'A',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink')))
%>% formatStyle(
'B',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink'))
)%>% formatStyle(
'C',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink'))
)
colors <- with(df, ifelse(X > -4 & X < 4 & Y < 10,
"pink",
ifelse(Y > 10,
"blue", "white")))
rgbcolors <- apply(grDevices::col2rgb(colors), 2,
function(rgb) sprintf("rgb(%s)", paste(rgb, collapse=",")))
columns <- c(2,3) # columns X and Y
jscode <-
paste("function(row, data, index) {",
sprintf("var colors=%s;\n%s",
sprintf("[%s]",
paste(sprintf("'%s'", rgbcolors), collapse=", ")),
paste(sprintf("$(this.api().cell(index, %s).node()).css('background-color', colors[index]);",
columns), collapse="\n")),
"}", sep="\n")
datatable(df, escape=FALSE,
options = list(rowCallback=JS(jscode))
)
jscode <- "function(row, data, index) {
var colors = ['rgb(255,192,203)', 'rgb(255,255,255)', 'rgb(0,0,255)', 'rgb(0,0,255)', 'rgb(0,0,255)', 'rgb(0,0,255)', 'rgb(255,192,203)', 'rgb(0,0,255)', 'rgb(255,255,255)', 'rgb(255,255,255)'];
$(this.api().cell(index, 2).node()).css('background-color', colors[index]);
$(this.api().cell(index, 3).node()).css('background-color', colors[index]);
}"
先感謝您
從...開始
datatable(df, escape=FALSE,
options = list(rowCallback=JS(jscode)))
並添加formatStyle
。
library(DT)
df <- data.frame(
id = 1:10,
X = c(-2, 4, 40, -0.1228, 2.9, 9, 2.7, 2.7, 31, -30),
Y = c(-18.9, -19.5, 19.6, 12, 11.1, 73, 4.3, 39, 2.5, 1.6),
A = c(-7.3, 5.1 ,0.12, 15, 21, 1.2, -0,07, 4.3, 39),
B = c(-18.9, 0.12, 15, 11.1, 73, -2, 4, 40, -19.5, 19.6),
C = c(4.3, 39, 2.5, 1.6, -7.3, 6, 5.1 ,0.12, -0.07, 4.3)
)
colors <- with(df, ifelse(X > -4 & X < 4 & Y < 10,
"pink",
ifelse(Y > 10,
"blue", "white")))
rgbcolors <- apply(grDevices::col2rgb(colors), 2,
function(rgb) sprintf("rgb(%s)", paste(rgb, collapse=",")))
columns <- c(2,3) # columns X and Y
jscode <-
paste("function(row, data, index) {",
sprintf("var colors=%s;\n%s",
sprintf("[%s]",
paste(sprintf("'%s'", rgbcolors), collapse=", ")),
paste(sprintf("$(this.api().cell(index, %s).node()).css('background-color', colors[index]);",
columns), collapse="\n")),
"}", sep="\n")
datatable(df, escape=FALSE,
options = list(rowCallback=JS(jscode))) %>%
formatStyle(
'A',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink'))) %>%
formatStyle(
'B',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink'))) %>%
formatStyle(
'C',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink'))
)
我提供的第一個解決方案可以正常工作,但是代碼不可讀。 這是一個更清潔的解決方案。
library(DT)
df <- data.frame(
id = 1:10,
X = c(-2, 4, 40, -0.1228, 2.9, 9, 2.7, 2.7, 31, -30),
Y = c(-18.9, -19.5, 19.6, 12, 11.1, 73, 4.3, 39, 2.5, 1.6),
A = c(-7.3, 5.1 ,0.12, 15, 21, 1.2, -0,07, 4.3, 39),
B = c(-18.9, 0.12, 15, 11.1, 73, -2, 4, 40, -19.5, 19.6),
C = c(4.3, 39, 2.5, 1.6, -7.3, 6, 5.1 ,0.12, -0.07, 4.3)
)
jscode <- "function(settings) {
var table = settings.oInstance.api();
var nrows = table.rows().count();
for(var i=0; i<nrows; i++){
var cell1 = table.cell(i,2);
var cell2 = table.cell(i,3);
var X = cell1.data(); var Y = cell2.data();
var bgcolor = 'white';
if(X > -4 && X < 4 && Y < 10){
bgcolor = 'pink';
}else if(Y > 10){
bgcolor = 'blue';
}
cell1.node().style.backgroundColor = bgcolor;
cell2.node().style.backgroundColor = bgcolor;
}
}"
datatable(df, escape=FALSE,
options = list(initComplete=JS(jscode))) %>%
formatStyle(
'A',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink'))) %>%
formatStyle(
'B',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink'))) %>%
formatStyle(
'C',
target = 'cell',
backgroundColor = styleInterval(3, c('green','pink'))
)
