Create Color Swatch Table

Creates a visual table displaying color names, hex codes, and color swatches. Requires the gt package to be installed.

Usage

create_color_table(df)

Arguments

df

A data frame with at minimum a column named hex containing hexadecimal color codes. Any additional columns will be included in the table. The first column (if not hex) will be automatically labeled as "Color Name" in the output table, regardless of its original name.

Value

A gt table object displaying the colors with visual swatches. The table will have columns for color names (if provided), hex codes, and a color swatch column where each cell is filled with the corresponding color.

Details

This function creates an enhanced table using the gt package. The table includes:

• Color names (if the name column exists in the input)

• Hexadecimal color codes

• Visual color swatches (cells filled with the actual colors)

The gt package must be installed to use this function. If it's not installed, the function will provide instructions on how to install it.

You can pass the output of get_color_data directly to this function, or create a custom data frame with your own color selection.

Examples

# Create a table with a few colors
colors_df <- data.frame(
  name = c("red", "blue", "forestgreen"),
  hex = c("#FF0000", "#0000FF", "#228B22")
)

# Only run if gt is available
if (requireNamespace("gt", quietly = TRUE)) {
  create_color_table(colors_df)

  # Use with get_color_data() - show first 10 colors
  all_colors <- get_color_data()
  create_color_table(head(all_colors, 10))

  # Create a table with only specific colors
  blue_colors <- all_colors[grepl("blue", all_colors$name), ]
  create_color_table(head(blue_colors, 20))

  # Minimal example with just hex codes
  hex_only <- data.frame(hex = c("#FF0000", "#00FF00", "#0000FF"))
  create_color_table(hex_only)
}
