用expss封装调整柱宽

Question

我一直经常使用expss，发现它非常有用，但是，在某些情况下，列值是长字符串，不适合默认的列宽度。

例如，下面的图像显示一个需要加宽的列。可以使用expss中的哪些expss选项来拓宽列？

​

Answer 1

有几种方法可以增加第一列的宽度。尝试以下方法之一：

library(expss)
expss_output_viewer()

data(mtcars)
mtcars = apply_labels(mtcars,
                      mpg = "Miles/(US) gallon",
                      cyl = "Number of cylinders",
                      disp = "Displacement (cu.in.)",
                      hp = "Gross horsepower",
                      drat = "Rear axle ratio",
                      wt = "Weight (1000 lbs)",
                      qsec = "1/4 mile time",
                      vs = "Engine",
                      vs = c("V-engine" = 0,
                             "Straight engine" = 1),
                      am = "Transmission",
                      am = c("Automatic" = 0,
                             "Manual"=1),
                      gear = "Number of forward gears",
                      carb = "Number of carburetors"
)


# straightforward column width adjustment
calc_cro_cpct(mtcars, list(vs, am), list(total(), vs %nest% am)) %>%
    htmlTable(., css.cell = c("width: 250px", # first column width
                              rep("width: 50px", ncol(.) - 1)) # other columns width
    )

# row labels padding
calc_cro_cpct(mtcars, list(vs, am), list(total(), vs %nest% am)) %>%
    htmlTable(padding.rgroup = paste(rep(" ", 20), collapse = ""))

# disable row grouping
calc_cro_cpct(mtcars, list(vs, am), list(total(), vs %nest% am)) %>%
    htmlTable(row_groups = FALSE)

参数css.cell和padding.rgroup记录在htmlTable包中，expss用于呈现htmlTable表示(参见?htmlTable::htmlTable)。
