Table Element Demo With Sorting
The data for the table is assumed to have HEADERS across the first row.
This is often the case for CSV files or spreadsheets
In release 4.48.0 a new enable_click_events parameter was added to the Table Element
This enables you to click on Column Headers and individual cells as well as the standard Row selection
This demo shows how you can use these click events to sort your table by columns
