Building on the foundation of the previous {gt} lesson — which focused on table structure and manipulation—I learned how to use the {gt} package to polish, style, and customize tables, enhancing the quality and efficiency of data reports.

Key Skills Gained:

  1. Applying Pre-Defined Themes (opt_stylize)
  • Learned to apply pre-defined styles and color themes to tables using the opt_stylize() function. Explored different style numbers and color choices to enhance visual appeal.
  1. Formatting Table Values (data_color)
  • Used the data_color() function to highlight key values in specific columns, making large datasets more interpretable.
  1. Conditional Formatting (tab_style)
  • Mastered conditional formatting by applying styles to table cells when they meet specific conditions or thresholds.
  1. Enhancing Table Text (Fonts & Colors)
  • Customized table titles, subtitles, and other text elements with different fonts and colors using gt::tab_style().
  1. Adding Borders (tab_style & cell_borders)
  • Learned to draw borders within tables to highlight specific sections, adjusting line color and thickness for better readability.
