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
