Html export - export table html and css
Use the dropdowns to change table style and theme, then click the Reload button. This is the only roundtrip done back to EPPlus. Change the appearance of the table by checking/unchecking the checkboxes.
All CSS classes needed to style the table are exported from EPPlus and based on Excels table styles and themes. You can use the dev tools of your favorite browser to see how the classes are applied to the table.
