Table is used for representing data or components in a pageable and selectable table.

Scalability of the Table is largely dictated by the container. A table does not have a limit for the number of items and is just as fast with hundreds of thousands of items as with just a few. The current GWT implementation with scrolling however limits the number of rows to around 500000, depending on the browser and the pixel height of rows.

Components in a Table will not have their caption nor icon rendered.

Since:

3.0

setColumnWidth

public void setColumnWidth(Object propertyId,
                           int width)

Sets columns width (in pixels). Theme may not necessary respect very small or very big values. Setting width to -1 (default) means that theme will make decision of width.

Column can either have a fixed width or expand ratio. The latter one set is used. See @link setColumnExpandRatio(Object, float).

Parameters:: propertyId - colunmns property id; width - width to be reserved for colunmns content
Since:: 4.0.3

setColumnExpandRatio

public void setColumnExpandRatio(Object propertyId,
                                 float expandRatio)

Sets the column expand ratio for given column.

Expand ratios can be defined to customize the way how excess space is divided among columns. Table can have excess space if it has its width defined and there is horizontally more space than columns consume naturally. Excess space is the space that is not used by columns with explicit width (see setColumnWidth(Object, int)) or with natural width (no width nor expand ratio).

By default (without expand ratios) the excess space is divided proportionally to columns natural widths.

Only expand ratios of visible columns are used in final calculations.

Column can either have a fixed width or expand ratio. The latter one set is used.

A column with expand ratio is considered to be minimum width by default (if no excess space exists). The minimum width is defined by terminal implementation.

If terminal implementation supports re-sizable columns the column becomes fixed width column if users resizes the column.

Parameters:: propertyId - columns property id; expandRatio - the expandRatio used to divide excess space for this column

getColumnExpandRatio

public float getColumnExpandRatio(Object propertyId)

Gets the column expand ratio for a columnd. See setColumnExpandRatio(Object, float)

Returns:: the Length of one page.

setPageLength

public void setPageLength(int pageLength)

Sets the page length.

Setting page length 0 disables paging. The page length defaults to 15.

If Table has width set (AbstractComponent.setWidth(float, int) ) the client side may update the page length automatically the correct value.

Parameters:: pageLength - the length of one page.

setCacheRate

public void setCacheRate(double cacheRate)

This method adjusts a possible caching mechanism of table implementation.

Discards and recreates the internal row cache. Call this if you make changes that affect the rows but the information about the changes are not automatically propagated to the Table.

Do not call this e.g. if you have updated the data model through a Property. These types of changes are automatically propagated to the Table.

A typical case when this is needed is if you update a generator (e.g. CellStyleGenerator) and want to ensure that the rows are redrawn with new styles.

Note that calling this method is not cheap so avoid calling it unnecessarily.

addGeneratedColumn

public void addGeneratedColumn(Object id,
                               Table.ColumnGenerator generatedColumn)

Adds a generated column to the Table.

A generated column is a column that exists only in the Table, not as a property in the underlying Container. It shows up just as a regular column.

A generated column will override a property with the same id, so that the generated column is shown instead of the column representing the property. Note that getContainerProperty() will still get the real property.

Table will not listen to value change events from properties overridden by generated columns. If the content of your generated column depends on properties that are not directly visible in the table, attach value change listener to update the content on all depended properties. Otherwise your UI might not get updated as expected.

Also note that getVisibleColumns() will return the generated columns, while getContainerPropertyIds() will not.

Parameters:: id - the id of the column to be added; generatedColumn - the Table.ColumnGenerator to use for this column

getColumnGenerator

public Table.ColumnGenerator getColumnGenerator(Object columnId)
                                         throws IllegalArgumentException

Returns the ColumnGenerator used to generate the given column.

public boolean removeGeneratedColumn(Object columnId)

Removes a generated column previously added with addGeneratedColumn.

Parameters:: columnId - id of the generated column to remove
Returns:: true if the column could be removed (existed in the Table)

getVisibleItemIds

public Collection<?> getVisibleItemIds()

Returns item identifiers of the items which are currently rendered on the client.

Note, that some due to historical reasons the name of the method is bit misleading. Some items may be partly or totally out of the viewport of the table's scrollable area. Actually detecting rows which can be actually seen by the end user may be problematic due to the client server architecture. Using getCurrentPageFirstItemId() combined with getPageLength() may produce good enough estimates in some situations.
