// - outer_size.x = 0.0f -> Auto width. Generally use all available width. When NOT using scrolling and NOT using any Stretch column, use only necessary width, otherwise same as -FLT_MIN.
// - outer_size.x > 0.0f -> Fixed width.
// Y with ScrollX/ScrollY disabled: we output table directly in current window
// - outer_size.y < 0.0f -> Bottom-align (but will auto extend, unless NoHostExtendV is set)

// - outer_size.y < 0.0f -> Bottom-align (but will auto extend, unless _NoHostExtendY is set). Not meaningful is parent window can vertically scroll.

// - outer_size.y > 0.0f -> Set Minimum height (but will auto extend, unless _NoHostExtenY is set)
// Y with ScrollX/ScrollY enabled: using a child window for scrolling
// - outer_size.y < 0.0f -> Bottom-align
// - outer_size.y < 0.0f -> Bottom-align. Not meaningful is parent window can vertically scroll.
// - outer_size.y = 0.0f -> Bottom-align, consistent with BeginChild(). Not recommended unless table is last item in parent window.
// - outer_size.y > 0.0f -> Set Exact height. Recommended when using Scrolling on any axis.
// In theory ImGuiTableFlags_NoHostExtendY could be the default and any non-scrolling tables with outer_size.y != 0.0f would use exact height.
// This would be consistent but perhaps less useful and more confusing (as vertically clipped items are not easily noticeable)
