You can save column width, height as properties in a file.
columnNames=new String[table.getColumnCount()];
for (int i=0;i<columnNames.length;i=i+1)
      columnNames[ i ]=table.getColumnModel().getColumn(i).getHeaderValue().toString();
data=new String[columnNames.length*table.getRowCount()];
j=0;
for (int i=0;i< table.getRowCount();i=i+1)
data[j]=table.getValueAt(i,0).toString();
data[j+1]=table.getValueAt(i,1).toString();
data[j+2]=table.getValueAt(i,2).toString();
j=j+3;//for 3 Cols
File file = new File("myTable.CSV");
String fileData;
if (file != null)
     try
          BufferedWriter bufferedWriter = new BufferedWriter(new FileWriter(file,true));
          PrintWriter fileWriter = new PrintWriter(bufferedWriter);
          System.out.println("Column Headers ");
               for(int j=0; j <  table.getColumnCount(); ++j)
                                fileData=columnNames[ i ];
                    fileWriter.print(fileData+",");
        System.out.println("Done.... ");
          fileWriter.println("");
          System.out.println("Exporting Data ");
          for(int i=0; i<table.getRowCount(); ++i)
               for(int j=0; j < table.getColumnCount(); ++j)
                    fileData = table.getValueAt(i,j).toString();
                    fileWriter.print(fileData+",");
               fileWriter.println("");
          fileWriter.close();
        System.out.println("Done.... ");--
you can save JTable in CSV format.
while reading just use readLine and then use StringTokenizer
