This is a multi axis scrollable data table, that allows you to scroll on both the vertical and horizontal axis, with the header remaining static on the vertical axis. Please look at the demo below.

Common Issues

1. Loading too many records: As with any list of values/records, adding too many records to the underlying model will overwhelm you app. Remember that this table will load all the rows in your model, whether they are visible on the screen or not. This is unlike other widgets like the ListView.builder which only paints items when they are scrolled into view. In this regard, only load a few records at a time by implementing your own pagination. My recommendation would be 20 - 30 records in mobile apps, and up to 50 for web apps. You can do your own tests to see how many your app can handle without stuttering.
