Table class
A widget that uses the table layout algorithm for its children.
To create a local project with this code sample, run:
flutter create --sample=widgets.Table.1 mysample
If you only have one row, the Row widget is more appropriate. If you only have one column, the SliverList or Column widgets will be more appropriate.
Rows size vertically based on their contents. To control the individual column widths, use the columnWidths property to specify a TableColumnWidth for each column. If columnWidths is null, or there is a null entry for a given column in columnWidths, the table uses the defaultColumnWidth instead.
By default, defaultColumnWidth is a FlexColumnWidth. This TableColumnWidth divides up the remaining space in the horizontal axis to determine the column width. If wrapping a Table in a horizontal ScrollView, choose a different TableColumnWidth, such as FixedColumnWidth.
For more details about the table layout algorithm, see RenderTable. To control the alignment of children, see TableCell.

Methods
-
createElement(
) → RenderObjectElement -
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
override
-
createRenderObject(
BuildContext context) → RenderTable -
Creates an instance of the RenderObject class that this
RenderObjectWidget represents, using the configuration described by this
RenderObjectWidget.
override
-
debugDescribeChildren(
) → List< DiagnosticsNode> -
Returns a list of DiagnosticsNode objects describing this node's
children.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
didUnmountRenderObject(
covariant RenderObject renderObject) → void -
A render object previously associated with this widget has been removed
from the tree. The given RenderObject will be of the same type as
returned by this object's createRenderObject.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(
{DiagnosticLevel minLevel = DiagnosticLevel.info}) → String -
A string representation of this object.

toStringShort(
) → String -
A short, textual description of this widget.
inherited
-
updateRenderObject(
BuildContext context, covariant RenderTable renderObject) → void -
Copies the configuration described by this RenderObjectWidget to the
given RenderObject, which will be of the same type as returned by this
object's createRenderObject.
