Question

我可以用 CSS 来样式单元格, 但如果我想用不同的样式( 如使用不同的文字颜色) 来换一个列, 则会怎样。

也许我漏了点什么

You should to use TableColumn#setCellFactory() to customize cell item rendering.
For example, datamodel with like this Person class:

// init code vs..
TableColumn firstNameCol = new TableColumn("First Name");
firstNameCol.setMinWidth(100);
firstNameCol.setCellValueFactory(new PropertyValueFactory<Person, String>("firstName"));
firstNameCol.setCellFactory(getCustomCellFactory("green"));

TableColumn lastNameCol = new TableColumn("Last Name");
lastNameCol.setMinWidth(100);
lastNameCol.setCellValueFactory(new PropertyValueFactory<Person, String>("lastName"));
lastNameCol.setCellFactory(getCustomCellFactory("red"));

table.setItems(data);
table.getColumns().addAll(firstNameCol, lastNameCol);

// scene create code vs..

和通用 getCustomCellFactory () 方法 :

private Callback<TableColumn<Person, String>, TableCell<Person, String>> getCustomCellFactory(final String color) {
        return new Callback<TableColumn<Person, String>, TableCell<Person, String>>() {

            @Override
            public TableCell<Person, String> call(TableColumn<Person, String> param) {
                TableCell<Person, String> cell = new TableCell<Person, String>() {

                    @Override
                    public void updateItem(final String item, boolean empty) {
                        if (item != null) {
                            setText(item);
                            setStyle("-fx-text-fill: " + color + ";");
                        }
                    }
                };
                return cell;
            }
        };
    }
