Use reactableTheme() to customize the default styling of a table. You can set theme variables to change the default styles, or add custom CSS to specific elements of the table.

The color variables are specified as character strings of CSS color values. The width and padding variables are specified as either character strings of CSS width and padding values, or numeric pixel values. The style arguments take custom CSS as named lists of camelCased properties.

To set the default theme for all tables, use the global reactable.theme option.
