This library helps you create sortable tables. The crucial feature is that it
|
|
|
|
|
lets you own your data separately and keep it in whatever format is best for
|
|
|
|
|
you. This way you are free to change your data without worrying about the table
|
|
|
|
|
“getting out of sync” with the data. Having a single source of
|
|
|
|
|
truth is pretty great!
