Similar to the post "
Apply style sheet on ListView to hide empty cells", we can create our custom css to set a specific color for all empty.
 |
| Hide empty cell of TableView with CSS |
Modify from last article "
Detect mouse click on JavaFX TableView and get the details of the clicked item".
Create javafx_testtableview/style_tableview.css file, copy the code from
Example 26-3 Setting Color for Empty Rows in a Table View of
Customization of UI Controls.
.table-row-cell:empty {
-fx-background-color: lightyellow;
}
.table-row-cell:empty .table-cell {
-fx-border-width: 0px;
}
Apply css file on the TabletView, by calling:
tableView.getStylesheets().add("javafx_testtableview/style_tableview");
Also modify handle(MouseEvent t) of MyEventHandler to check IndexOutOfBoundsException on recordList.get(index).
