```{r}
library(gt)
gt(head(mtcars)) |>
    tab_options(table.width = pct(100), column_labels.font.weight = "bold") |>
    cols_align(align = "left")


gt(head(mtcars)) |>
    tab_options(table.width = px(600), column_labels.font.weight = "bold") |>
    cols_align(align = "left")
```

The above code does not take effect on the table width. How to adjust the table width?
