我正在尝试使用rhandsontable
库生成一个表,其中我结合了两个包的漂亮功能:(1)使用客户renderer
参数进行行突出显示,以及(2)布尔字段的复选框列类型。
单独使用这两种功能都可以。例如,下面显示行突出显示的工作原理:
library(rhandsontable)
df = data.frame(val = 1:10, bool = TRUE, big = LETTERS[1:10],
small = letters[1:10],
stringsAsFactors = FALSE)
row_highlight = c(5, 7)
rhandsontable(df,
row_highlight = row_highlight) %>%
hot_cols(renderer = "
function(instance, td, row, col, prop, value, cellProperties) {
Handsontable.renderers.TextRenderer.apply(this, arguments);
tbl = this.HTMLWidgets.widgets[0]
hrows = tbl.params.row_highlight
hrows = hrows instanceof Array ? hrows : [hrows]
if (hrows.includes(row)) {
td.style.background = 'pink';
}
return td;
}")
以下显示复选框功能的工作原理:
library(rhandsontable)
df = data.frame(val = 1:10, bool = TRUE, big = LETTERS[1:10],
small = letters[1:10],
stringsAsFactors = FALSE)
rhandsontable(df, row_highlight = row_highlight) %>%
hot_col(col = 'bool', type = 'checkbox')
我的问题:如何结合这两个功能(即生成一个带突出显示的行和功能复选框的表)?
有人会认为以下内容可行,但复选框不会呈现(而是显示为true
和false
):
library(rhandsontable)
df = data.frame(val = 1:10, bool = TRUE, big = LETTERS[1:10],
small = letters[1:10],
stringsAsFactors = FALSE)
row_highlight = c(5, 7)
rhandsontable(df,
row_highlight = row_highlight) %>%
hot_cols(renderer = "
function(instance, td, row, col, prop, value, cellProperties) {
Handsontable.renderers.TextRenderer.apply(this, arguments);
tbl = this.HTMLWidgets.widgets[0]
hrows = tbl.params.row_highlight
hrows = hrows instanceof Array ? hrows : [hrows]
if (hrows.includes(row)) {
td.style.background = 'pink';
}
return td;
}") %>%
hot_col(col = 'bool', type = 'checkbox')
有没有办法在R的rhandsontable中结合使用复选框和行突出显示?
答案 0 :(得分:0)
应使用 text / numeric 和逻辑变量将不同的渲染器应用于列,以便将复选框功能和突出显示的行组合在一起。
library(rhandsontable)
df = data.frame(val = 1:10, bool = TRUE, big = LETTERS[1:10],
small = letters[1:10],
stringsAsFactors = FALSE)
row_highlight = c(5, 7)
rhandsontable(df,
row_highlight = row_highlight) %>%
hot_col(col = names(df)[!names(df) %in% "bool"],
renderer = "
function(instance, td, row, col, prop, value, cellProperties) {
Handsontable.renderers.TextRenderer.apply(this, arguments);
tbl = this.HTMLWidgets.widgets[0]
hrows = tbl.params.row_highlight
hrows = hrows instanceof Array ? hrows : [hrows]
if (hrows.includes(row)) {
td.style.background = 'pink';
}
return td;
}") %>%
hot_col(col = "bool",
renderer = "
function(instance, td, row, col, prop, value, cellProperties) {
Handsontable.renderers.CheckboxRenderer.apply(this, arguments);
tbl = this.HTMLWidgets.widgets[0]
hrows = tbl.params.row_highlight
hrows = hrows instanceof Array ? hrows : [hrows]
if (hrows.includes(row)) {
td.style.background = 'pink';
}
return td;
}")
