Topic: MDBDatatable not updating with React state
Bridget Melvin pro premium asked 2 years ago
Expected behavior
When the edit button is pressed within a table row, I edit "user permissions" and change the role from 'User' to 'Collaborator'. The table show reflect the updated user state. Console logs show react is properly updating the state per a complex change mechanism (modals, handlers, HOCs) and it reflects back properly in console logs within the parent component. But the table never updates this for the values. I am not including the higher order components with the change handler having console.logs show that the state is being properly updated and passed down to UsersTable.js
Actual behavior When the user with role 'User' (table column) has its permissions updated to reflect role = 'Collaborator', the table never reflects this change. That is, it stays the same.

This line:
tableData = {
columns: colData,
rows: usersData
}
will update your data, but it will not cause a rerender. That is why you have something like setTableData
. You should not update your state the way you did here.
