使用格式表 package 从 R 更改表格内容的字体大小

Question

假设一个 dataframe 如下：

df <- structure(list(week1 = c(30, 74.62, 189.93, 2394.91, 6095.8, 
2.88, 45.49), week2 = c(30, 88.4, 156.14, 2880.4, 5087.41, 7.98, 
44.97), change = structure(c(0, -0.1559, 0.2164, -0.1685, 
0.1982, -0.6391, 0.0114), formattable = list(formatter = "formatC", 
    format = list(format = "f", digits = 2L), preproc = "percent_preproc", 
    postproc = "percent_postproc"), class = c("formattable", 
"numeric"))), row.names = c("v1", "v2", "v3", "v4", "v5", "v6", "v7"), class = "data.frame")

我创建了一个带有formattable表的表格，代码如下：

formattable(df,
            list(~ formatter("span",
                             style = x ~ formattable::style(display = "block",
                                                            "border-radius" = "10px",
                                                            "padding" = "10px",
                                                            "text-align" = "center")),
              week2 = color_tile("white", "orange"),
              week1 = color_tile("white", "orange"),
              `change` = formatter("span",
                 style = ~ style(color = ifelse(`week2` > `week1`, "green", "red"), "font.weight" = "bold", "font.size" = "16px"),
                 ~ icontext(sapply(`change`, function(x) if (x < 0) "arrow-down" else if (x > 0) "arrow-up" else ""), `change`))))

出去：

我可以为change列的值设置字体大小，但现在我想将其应用于整个表，包括行名，我该怎么做？ 谢谢。

您可以在table.attr参数中全局定义表格的字体大小。
您可以通过在formatter参数中定义字体大小来覆盖某些列的这些设置。 就像您对change列所做的那样。

在下面的示例中，表格字体大小设置为 16px，就像change列一样。

df <- data.frame(week1 = c(30, 74.62, 189.93, 2394.91, 6095.8, 2.88, 45.49), 
                 week2 = c(30, 88.4, 156.14, 2880.4, 5087.41, 7.98, 44.97), 
                 change = c(0, -0.1559, 0.2164, -0.1685, 0.1982, -0.6391, 0.0114))
rownames(df) <- LETTERS[1:7]

formattable(df,
            list(week2 = color_tile("white", "orange"),
                 week1 = color_tile("white", "orange"),
                 `change` = formatter("span",
                                      style = ~ style(color = ifelse(`week2` > `week1`, "green", "red"), "font.weight" = "bold", "font.size" = "16px"),
                                      ~ icontext(sapply(`change`, function(x) if (x < 0) "arrow-down" else if (x > 0) "arrow-up" else ""), `change`))),
            table.attr = 'style="font-size: 16px;";\"')
