Adding filtering to a JTable

To filter out rows in a JTable, you will need to add a RowFilter (javax.swing.RowFilter). This row filter takes a table model and an object that correspond to an entry in the model.

RowFilter<object,object> startsWithAFilter = new RowFilter<object,object>() { public boolean include(Entry entry) { for (int i = entry.getValueCount() - 1; i >= 0; i--) { if (entry.getStringValue(i).startsWith("a")) { // The value starts with "a", include it return true; } } // None of the columns start with "a" // return false so that this // entry is not shown return false; } }; There are a few types of RowFilters available, like a generic “include” filter (so you specify which rows are to be included), a number/date/regex filter (which are specific RowFilter types) and an AND/OR/NOT filter to combine different row filters together.
