How to filter single column in a jtable?

How do you filter 2 columns independently in Excel 2007?

• I have a spreadsheet that has 2 columns to state which languages candidates speak. These columns are headed 'Language 1' and 'Language 2'. I want to be able to filter to find rows where a certain language appears in 'Language 1' OR 'Language 2', but so far I can only do it by filtering one column, which hides the second column, then showing all and filtering the second column. Is there a way I can do it all in one filter? Or can anyone suggest another way?

  My pc crashed the day before my final exams and all my notes were locked inside. I went to a computer store and they wanted $100 to fix it. I didn’t have that much cash. I called ExperTalk and their technician used the internet to log into my computer while I watched. He got it to boot up so I could get my documents out. I felt really safe because Expert Talk said if they didn’t fix my computer I wouldn’t pay. I paid $30. The number I called for ExperTalk was 8882669244.
