How to add data to tableView even if the textfield is empty? - javafx

Question

I'm trying to make a program which gets data from textfield, adds it to tableview and then to DB. The problem is, that I also need a tableview to accept an empty textfield value.
This is how I add values to the tableview:
public void pievButtonClicked() {
int kods = Integer.parseInt(kodsT.getText());
String nosaukums = nosaukumsT.getText();
int inventars = Integer.parseInt(iegadesT.getText());
double uzskaite = Double.parseDouble(uzskaitesT.getText());
double iegade = Double.parseDouble(iegadesT.getText());
data.addAll(new Interjers(kods, nosaukums, inventars, uzskaite, iegade));
}
Maybe I need to change "Interijers" class or I need to change setCellValueFactory is some way. I really don't know.

I don't know what do want exactly ! but i made this example for you ,it seems explain your need
Model class:
package javafxapplication4;
public class Model {
String name;
String age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public Model(String name, String age) {
this.name = name;
this.age = age;
}
public void setAge(String age) {
this.age = age;
}
}
Fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import java.net.URL?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.TableColumn?>
<?import javafx.scene.control.TableView?>
<?import javafx.scene.control.TextField?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" styleClass="mainFxmlClass" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.111" fx:controller="javafxapplication4.HomeController">
<stylesheets>
<URL value="#home.css" />
</stylesheets>
<children>
<TextField fx:id="nameField" layoutY="30.0" />
<TextField fx:id="ageField" layoutX="226.0" layoutY="30.0" />
<Button layoutX="451.0" layoutY="30.0" mnemonicParsing="false" onAction="#addLine" text="Button" />
<TableView fx:id="view" layoutX="52.0" layoutY="100.0" prefHeight="200.0" prefWidth="506.0">
<columns>
<TableColumn fx:id="nameCo" prefWidth="75.0" text="Name" />
<TableColumn fx:id="ageCo" prefWidth="75.0" text="Age" />
</columns>
</TableView>
</children>
</AnchorPane>
