How can I filter rows in a JTable?

Question

I have a JTable with many strings in it. I have created a textbox for user entry, above the table. I want a row filter which can remove the rows having strings entered by the user in the text box. Please help me out for this.

do you want to display only rows with the text or to not display rows with the text? – Braden

If you are allowed, you could use GlazedLists. It has samples about auto-completion and table filtering. – Mister

Answer 1

from here:
sorting and filtering

In the following example code, you explicitly create a sorter object so you can later use it to specify a filter:

MyTableModel model = new MyTableModel();
sorter = new TableRowSorter<MyTableModel>(model);
table = new JTable(model);
table.setRowSorter(sorter);

Then you filter based on the current value of a text field:

private void newFilter() {
    RowFilter<MyTableModel, Object> rf = null;
    //If current expression doesn't parse, don't update.
    try {
        rf = RowFilter.regexFilter(filterText.getText(),0);
    } catch (java.util.regex.PatternSyntaxException e) {
        return;
    }
    sorter.setRowFilter(rf);
}

This few line solution seems to work:

private void jTextField1ActionPerformed(java.awt.event.ActionEvent evt) 
{                                            
    TableRowSorter<TableModel> sorter = new TableRowSorter<TableModel>(((DefaultTableModel) jTable1.getModel())); 
    sorter.setRowFilter(RowFilter.regexFilter(jTextField1.getText()));

    jTable1.setRowSorter(sorter);
}

Answer 3

You can use JTable.setAutoCreateRowSorter which will use the default row sorter/filter of the JTable

Answer 4

To pick up the comment from kd304, you could use GlazedLists. There you'll use a FilterList as the input for your JTable, and the FilterList will take care of the rest.
