Class TableLayout
This Layout positions non-Link Parts into a table according to the values of Row, Column, RowSpan, ColumnSpan, Alignment, Stretch.
Namespace: Northwoods.Go.Layouts.Extensions
Assembly: TableAvalonia.dll
Syntax
public class TableLayout : LayoutRemarks
If the value of GraphObject.Stretch is not None, the Part will be sized according to the available space in the cell(s).
You can specify constraints for whole rows or columns by calling GetRowDefinition(int) or GetColumnDefinition(int) and setting one of the following properties: Alignment, Height, MaxHeight, MinHeight (or their column equivalents), Stretch, or in bulk by calling Add(params RowDefinition[]).
The DefaultAlignment and DefaultStretch properties apply to all parts if not specified on the individual Part or in the corresponding row or column definition.
At the current time, there is no support for separator lines (SeparatorStroke, SeparatorStrokeWidth, and SeparatorDashArray properties) nor background (Background and CoversSeparators properties). There is no support for Sizing, either.

Overrides
FindColumnForDocumentX(double)
Returns the column at a given x-coordinate in document coordinates.
Declaration
public int FindColumnForDocumentX(double x)Parameters

Returns
| Type | Description |
|---|---|
| int | a zero-based integer |
Remarks
This information is only valid when this layout has been performed and IsValidLayout is true.
If the point is to the left of column 0, this method returns -1. If the point is to the right of the last column, this returns the last column + 1.
