the problem when search in filterathid or filterforename , remove contents searching blank rows appear in code.

    sorter.setrowfilter     (         new rowfilter<tablemodel, integer>()              {             @override             public boolean include(rowfilter.entry<? extends tablemodel, ? extends integer> entry)                  {                     boolean included = true;                     object cellvalue = entry.getmodel().getvalueat(entry.getidentifier(), 0);                     if (cellvalue == null || cellvalue.tostring().trim().isempty())                      {                         included = false;                     }                     return included;                 }             }     ); 

i had used code remove blank rows after empty search seems stop working. issue?

merging 2 row filters jtable

you can combine multiple filters one. example uses "and" fileter, can use "or" filter:

list<rowfilter<object,object>> filters = new arraylist<rowfilter<object,object>>(2); filters.add(rowfilter.regexfilter(filtertext.gettext(), 0)); filters.add(rowfilter.regexfilter(filtertext.gettext(), 1)); rf = rowfilter.andfilter(filters); 

this example based on sorting , filtering demo swing tutorial.
