Create a matrix where each cell is selectable. Kind of like a spreadsheet with selectable cells!
This component could be fed by a regular data table of rows.
Our use case is: we'd like to see whether users have set availability in our app for each day of a week, so we'd have users as rows, and days of the week as columns.
We'd then like to be able to select multiple "user days" to and work with those days in retool.
