Usually 240 per 200 as minimum. Needs to be specified to the root of the container in the FXML.

Useful constants:

• USE_COMPUTED_SIZE = -1
• USE_PREFS_SIZE = -Infinity

minWidth and minHeight can use USE_PREFS_SIZE which means they'll match prefWidth and prefHeight. While USE_COMPUTED_SIZE might appear to be useful, in practice it rarely works, being either too greedy (masked buttons, ugly widgets) or allowing the window to hide the whole interface.

Property value factory work and can track changes from the original data (they use observables) but are not very flexible, are prone to typos/wrong names that are not detected by the compiler and don't work with records. Instead, if you do not need to track changes, try to use the following:

TableColumn<Person, String> lastColumn = new TableColumn<>("Last");
lastColumn.setCellValueFactory(
        p -> new SimpleStringProperty(p.getValue().last())
);

For other things than a string, use:

TableColumn<Person, Integer> ageColumn = new TableColumn<>("Age");
ageColumn.setCellValueFactory(
        p -> new SimpleIntegerProperty(p.getValue().age()).asObject()
);

There's also SimpleObjectProperty and so on...

One can do it with FXML only like:

<TableView fx:id="todoList">
    <columns>
        <TableColumn text="Name" minWidth="75.0" sortable="true">
            <cellValueFactory>
                <PropertyValueFactory property="name" />
            </cellValueFactory>
        </TableColumn>
        <TableColumn text="Date" minWidth="50.0" sortable="true">
            <cellValueFactory>
                <PropertyValueFactory property="date" />
            </cellValueFactory>
        </TableColumn>
    </columns>
</TableView>
