使用grid.table打印表格时，如何正确关闭行名？

Ah, I get it— that error happens because grid.table() doesn't accept a row.names argument directly, unlike some base R table-printing functions. Let's fix this properly with the package's built-in theme system, which controls all visual elements of the table.

The Simple Solution #

You can directly hide row names by modifying the table theme to turn off the row header (which holds the row names) display:

library(gridExtra)
library(grid)

d <- head(iris[,1:3])
# Hide row names by disabling the rowhead element in the theme
grid.table(d, theme = ttheme_default(rowhead = list(show = FALSE)))

Customizing Further (If You Want) #

If you want more control over the table's appearance while hiding row names, you can build a full custom theme. For example, adjusting cell colors or alignment along with hiding row names:

custom_table_theme <- ttheme_default(
  core = list(
    bg_params = list(fill = c("white", "#f8f8f8"), alpha = 0.9),
    fg_params = list(hjust = 0.5, x = 0.5)
  ),
  colhead = list(
    bg_params = list(fill = "#e0e0e0"),
    fg_params = list(fontface = "bold")
  ),
  rowhead = list(show = FALSE) # This line hides the row names
)

grid.table(d, theme = custom_table_theme)

Why Your Original Code Failed #

The row.names = FALSE argument works for functions like print.data.frame() or knitr::kable(), but grid.table() uses a theme-based system to manage every part of the table's look. Row names are part of the "rowhead" component in the theme, so we have to target that specifically to hide them.
