Demo Program - Table with checkboxes
|
|||
|
|
|
|||
|
|
This clever solution was sugged by GitHub user robochopbg.
|
|||
|
|
The beauty of the simplicity is that the checkbox is simply another column in the table. When the checkbox changes
|
|||
|
|
state, then the data in the table is changed and the table is updated in the Table element.
|
|||
|
|
A big thank you again to user robochopbg!
