It seems that you first create a table by passing data and columns, then create a model and set the model. When you pass column and row data in JTable constructor, then the table creates and uses DefaultTableModel that is initialized with that data. If you have a specialized model frandtabmodule that wraps around the original vector feeds there is no need to build an array and pass it to the table. Just use JTable default constructor and then call setModel, or use a constructor that takes a model as an argument.

See How to use Tables for more details and examples.

EDIT:

Not sure is that is the intention, but the posted code indicates that you want to use the vector elements as columns. If that is not the intention, then it seems you have a mix up of indexes while building an array. The first set of square brackets is for the rows and the second is for columns. For example: 

private static Object[][] vector2DArray(Vector<Object> sourceVector) {
    Object[][] rows = new Object[sourceVector.size()][1];

    for (int i = 0; i < sourceVector.size(); i++) {
        rows[i][0] = sourceVector.get(i);
    }

    return rows;
}

to load the table from an array A, if the table just create it, you can simply use:   

     table.setModel (new javax.swing.table.DefaultTableModel (
                 new String [] [] {
 {"2014-02-22", A.get(0)}
     }   ,          
                 new String [] {
             "Date", "Total" 
         }));

if not, you can use the DefaultTableModel class and its methods and AddColumn addRow
