Detailed Description

TableView is a layout container for aligning child actors in a grid like layout.

TableView constrains the x and y position and width and height of the child actors. z position and depth are left intact so that 3D model actors can also be laid out in a grid without loosing their depth scaling.

Per-child Custom properties for script supporting:

When an actor is add to the tableView through Actor::Add() instead of TableView::AddChild, the following custom properties of the actor are checked to decide the actor position inside the table.

These properties are registered dynamically to the child and is non-animatable.

| Property Name | Type | |-------------------------|-------------| | cellIndex | Vector2 | | rowSpan | float | | columnSpan | float | | cellHorizontalAlignment | string | | cellVerticalAlignment | string |

The rowSpan or columnSpan has integer value, but its type is float here due to the limitation of the builder's ability to differentiate integer and float from Json string. The available values for cellHorizontalAlignment are: left, center, right. The available values for cellVerticalAlignment are: top, center, bottom.
