Examples of org.apache.click.control.Table

org.apache.click.control.Table
eforge.net/projects/displaytag">DisplayTag like functionality. The design of the Table control has been informed by the excellent DisplayTag library.
Table Example
An example Table usage is provided below:
```
 public class CustomersPage extends BorderPage { public Table table = new Table(); public ActionLink deleteLink = new ActionLink("Delete", this, "onDeleteClick"); public CustomersPage() { table.setClass(Table.CLASS_ITS); table.setPageSize(4); table.setShowBanner(true); table.setSortable(true); table.addColumn(new Column("id")); table.addColumn(new Column("name")); Column column = new Column("email"); column.setAutolink(true); table.addColumn(column); table.addColumn(new Column("investments")); column = new Column("Action"); column.setDecorator(new LinkDecorator(table, deleteLink, "id")); column.setSortable(false); table.addColumn(column); } public boolean onDeleteClick() { Integer id = deleteLink.getValueInteger(); getCustomerService().deleteCustomer(id); return true; } public void onRender() { List customers = getCustomerService().getCustomersSortedByName(); table.setRowList(customers); } } 
```
CSS and JavaScript resources
The Table control makes use of the following resources (which Click automatically deploys to the application directory, /click):
- click/table.css
To import the Table CSS styles and any control JavaScript simply reference the variables $headElements and $jsElements in the page template. For example:
```
 <html> <head> $headElements </head> <body> $table $jsElements </body> </html> 
```
Table Styles
The table CSS style sheet is adapted from the DisplayTag screen.css style sheet and includes the styles:
- blue1
- blue2
- complex
- isi
- its
- mars
- nocol
- orange1
- orange2
- report
- simple
To use one of these CSS styles set the table "class" attribute. For example in a page constructor:
```
 public LineItemsPage() { Table table = new Table("table"); table.setClass(Table.CLASS_SIMPLE); .. } 
```
An alternative method of specifying the table class to use globally for your application is to define a table-default-class message property in your applications click-pages.properties file. For example:
```
 table-default-class=blue2 
```
Paging
Table provides out-of-the-box paging.
To enable Paging set the table's page size: {@link #setPageSize(int)} andmake the Table Banner visible: {@link #setShowBanner(boolean)}.
Table supports rendering different paginators through the method {@link #setPaginator(org.apache.click.control.Renderable) setPaginator}. The default Table Paginator is {@link TablePaginator}.
Sorting
Table also has built in column sorting.
To enable/disable sorting use {@link #setSortable(boolean)}.
Custom Parameters - preserve state when paging and sorting
Its often necessary to add extra parameters on the Table links in order to preserve state when navigating between pages or sorting columns.
One can easily add extra parameters to links generated by the Table through the Table's {@link #getControlLink() controlLink}.
For example:
```
 public CompanyPage extends BorderPage { // companyId is the criteria used to limit Table rows to clients from // the specified company. This variable could be selected from a drop // down list or similar means. public String companyId; public Table table = new Table(); public onInit() { // Set the companyId on the table's controlLink. If you view the // output rendered by Table note that the companyId parameter // is rendered for each Paging and Sorting link. table.getControlLink().setParameter("companyId", companyId); } ... public void onRender() { // Select only clients for the specified companyId List rowList = getCompanyDao().getCompanyClients(companyId); table.setRowList(rowList); } } 
```
Row Attributes
Sometimes it is useful to add HTML attributes on individual rows. For these cases one can override the method {@link #addRowAttributes(java.util.Map,java.lang.Object,int)}and add custom attributes to the row's attribute Map.
Large Datasets
For large datasets Table provides automatic pagination to display a limited number of rows per page. However the Table's {@link #setRowList(java.util.List) row list} must still contain all thedataset entries. With very large datasets (e.g. 100,000 rows), its not possible to retrieve that many rows from the database.
For these rarer cases a custom List implementation can be used as the Table's {@link #setRowList(java.util.List) row list}. The custom List will only be populated with the rows that must be displayed for the selected page.
A custom List has two responsibilities: it must override {@link java.util.List#size() List.size()} to return the total number of rows and it must override{@link java.util.List#get(int) List.get(index)} to ensure the List returns thecorrect row for the specified index.
A prerequisite for this strategy is that the total number of rows must be available beforehand, otherwise it won't be possible to calculate the {@link #getLastRow() last row} value.
The methods {@link #getFirstRow()}, {@link #getLastRow()} and{@link #getPageSize()} provides you with the necessary information to limitthe database rows to the selected page.
Please see the Large Dataset Demo which provides a custom List implementation as described above.
