# Titanium.UI.TableViewSection
A table view section is a container within a table used to organize table view rows.
# Overview
Use the Titanium.UI.createTableViewSection method or <TableViewSection>
Alloy element to
create a TableViewSection
.
Before the table is rendered, the TableViewSection
Titanium.UI.TableViewSection.add
method may be used to add Titanium.UI.TableViewRow objects to a section. After
it is rendered, one of the TableView
Titanium.UI.TableView.insertRowBefore,
Titanium.UI.TableView.insertRowAfter, or
Titanium.UI.TableView.appendRow methods must be used instead.
To remove a row from a section after the table is rendered, use the TableView
Titanium.UI.TableView.deleteRow method.
In order for a section to be visible, either its headerTitle
or headerView
property must be
configured.
Starting in Release 3.0, you can directly manipulate the sections in a table using the
following TableView
APIs:
- To set all sections in a table view at one time, use the
TableView
Titanium.UI.TableView.sections property. - To add an individual section after a table view is rendered, use either the
TableView
Titanium.UI.TableView.insertSectionBefore or Titanium.UI.TableView.insertSectionAfter method. - To add one or more sections to the end of a table view after it is rendered, use the
TableView
Titanium.UI.TableView.appendSection method. - To remove an individual section after a table view is rendered, use the
TableView
Titanium.UI.TableView.deleteSection method.
Prior to Release 3.0, adding or removing sections individually is not supported. Instead, use the
TableView
Titanium.UI.TableView.data property to refresh the whole table with a
new section layout.
See the description and examples sections of Titanium.UI.TableView for more details
about how to use TableViewSection
.
Note: On some platforms, TableViewSection
may be implemented as a type of view
(that is, an object that inherits from Titanium.UI.View). However, this is an
implementation detail. For portability, you should only use the documented APIs on
table view sections.
# Properties

Title of this section footer.
Using this property and footerView
together is not supported. Use one or the other.
On Android, must be set at creation.
# footerView

Using this property and footerTitle
together is not supported. Use one or the other.
On Android, must be set at creation.
# headerTitle

In Alloy, you can use a <HeaderView>
element inside a <TableViewSection>
element:
<Alloy>
<TableView filterAttribute="title">
<SearchBar platform="android,ios"/>
<TableViewSection>
<HeaderView>
<View backgroundColor="#a00" height="50dp"/>
</HeaderView>
<FooterView>
<View backgroundColor="#0a0" height="50dp"/>
</FooterView>
<TableViewRow title="Row 1"/>
<TableViewRow title="Row 2"/>
<TableViewRow title="Row 3"/>
</TableViewSection>
</TableView>
</Alloy>
# Methods
# add
Adds a table view row to this section.
Should be called before adding the section to a table. Calling add
on a section
that's already been added to a table does not update the table.
To add a row to a section after it's been added to a table, call one of the
TableView
methods, insertRowBefore,
insertRowAfter, or
appendRow.
On Android, it is possible to update a section by adding or removing rows and then
resetting the table view's data
property. However, this approach is not
portable and is not recommended.

---|---|---|
row | Titanium.UI.TableViewRow | Row to add. |
Returns
- Type

# remove
Removes a table view row from this section.
Should be called before a section is added to a table. Calling remove

a section that's already been added to a table may throw an exception.
To delete a row once the section is added to a table, use the TableView
deleteRow method.
On Android, it is possible to update a section by adding or removing rows and then
resetting the table view's data
