How can i clear the all contents of the cell data in every row in my tableview in JAVA FX

Question

I am finding hard to clear the table contents in my table. I have tried this code.

for ( int i = 0; i<resultTable.getItems().size(); i++) {
    resultTable.getItems().clear();
}

To clarify my question, the problem I am having is that i want to delete the values in my table. This was the first code i used;

public void removeRow(){
    allFiles = table.getItems(); fileSelected = table.getSelectionModel().getSelectedItems(); 
    fileSelected.forEach(allFiles :: remove); 
}

But it only removes a particular selected row. I want to clear all the rows and leave the table empty at once, without having to select any row. I tried to use this code;

public void removeAllRows(){
    for ( int i = 0; i<resultTable.getItems().size(); i++) {
        resultTable.getItems().clear(); 
    } 
}

but it does not clear all the rows in the table

My plan is to use this method as an action for a button. e.g

Button btn = new ("Clear Table");
btn..setOnAction(e->{removeAllRows();});

When this button is clicked, it should delete all rows in the table at once.

Answer 1

tableView.getItems().clear()

Will do the trick

Answer 2

Try using the following: Name "tableView" to whatever your FXMLtable is called

for ( int i = 0; i<tableView.getItems().size(); i++) {
    tableView.getItems().clear();
}
