  <h3>e906. Creating a JTable Component</h3>

The following creates a table that uses an efficient underlying
storage implementation. Although cell values can be changed, rows and
columns cannot be added or deleted.  


<pre>    // Create with initial data
    Object[][] cellData = {
        {<font color="#0066ff"><i>"row1-col1"</i></font>, <font color="#0066ff"><i>"row1-col2"</i></font>},
        {<font color="#0066ff"><i>"row2-col1"</i></font>, <font color="#0066ff"><i>"row2-col2"</i></font>}};
    String[] columnNames = {<font color="#0066ff"><i>"col1"</i></font>, <font color="#0066ff"><i>"col2"</i></font>};
    
    JTable table = new JTable(cellData, columnNames);
</pre>
The following creates tables that allow rows and columns to be added or deleted:

<pre>    // Create a table with empty cells
    int rows = <font color="#0066ff"><i>10</i></font>;
    int cols = <font color="#0066ff"><i>5</i></font>;
    table = new JTable(rows, cols);
    
    // Create a table with initial data
    Vector rowData = new Vector();
    for (int i=0; i&lt;cellData.length; i++) {
        Vector colData = new Vector(Arrays.asList(cellData[i]));
        rowData.add(colData);
    }
    Vector columnNamesV = new Vector(Arrays.asList(columnNames));
    
    table = new JTable(rowData, columnNamesV);
</pre>
<P><table width="600" CELLSPACING="0" CELLPADDING="2" BORDER="0">
