DataEditor
Basic Usage
HTML/CSS Prerequisites
Currently the Grid depends on there being a root level "portal" div in your HTML. Insert this snippet as the last child of your <body>
tag:
Once you've got that done, the easiest way to use the Data Grid is to give it a fixed size:
Changes to your data
The Grid will never change any of your underlying data. You have to do so yourself when one of the callbacks is invoked. For example, when the user edits the value in a cell, the Grid will invoke the onCellEdited
callback. If you don't implement that callback, or if it doesn't change the undelying data to the new value, the Grid will keep displaying the old value.
