Moving a column requires the index of the column to be moved and a position specified. The index of a column is 0-based; the first column has index 0. Positions are locations between columns. For example, if there are 2 columns in a table, there are 3 possible position - - 0, 1,and 2. Moving a column to position 0 makes the column the first column. Moving a column to position 2 makes the column the last column. 
    int rows = 10;
    int cols = 5;
    JTable table = new JTable(rows, cols);
    
    // Move the last visible column so it becomes the first visible column
    int vSrcColIndex = table.getColumnCount()-1;
    int vDstColIndex = 0;
    table.moveColumn(vSrcColIndex, vDstColIndex);
