e906. Creating a JTable Component
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.
// Create with initial data
Object[][] cellData = {
{"row1-col1", "row1-col2"},
{"row2-col1", "row2-col2"}};
String[] columnNames = {"col1", "col2"};
JTable table = new JTable(cellData, columnNames);
The following creates tables that allow rows and columns to be added or deleted:
// Create a table with empty cells
int rows = 10;
int cols = 5;
table = new JTable(rows, cols);
// Create a table with initial data
Vector rowData = new Vector();
for (int i=0; i<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);
