/** |
|
36 |
* <p> |
|
37 |
* Implements View interface for a table, that is composed of an |
|
38 |
* element structure where the child elements of the element |
|
39 |
* this view is responsible for represent rows and the child |
|
40 |
* elements of the row elements are cells. The cell elements can |
|
41 |
* have an arbitrary element structure under them, which will |
|
42 |
* be built with the ViewFactory returned by the getViewFactory |
|
43 |
* method. |

* </pre> |
|
55 |
* <p> |
|
56 |
* This is implemented as a hierarchy of boxes, the table itself |
|
57 |
* is a vertical box, the rows are horizontal boxes, and the cells |
|
58 |
* are vertical boxes. The cells are allowed to span multiple |
|
59 |
* columns and rows. By default, the table can be thought of as |
|
60 |
* being formed over a grid (i.e. somewhat like one would find in |
|
61 |
* gridbag layout), where table cells can request to span more |
|
62 |
* than one grid cell. The default horizontal span of table cells |
|
63 |
* will be based upon this grid, but can be changed by reimplementing |
|
64 |
* the requested span of the cell (i.e. table cells can have independant |
|
65 |
* spans if desired). |
