// About 'outer_size':
// Its meaning needs to differ slightly depending of if we are using ScrollX/ScrollY flags.
// Default value is ImVec2(-FLT_MIN, 0.0f). When binding this in a scripting language please follow this default value.
// Default value is ImVec2(0.0f, 0.0f).
// X
// - outer_size.x < 0.0f -> Right-align from window/work-rect right-most edge. With -FLT_MIN will right-align exactly on right-most edge. With -1.0f will right-align one pixel away from right-most edge.
// - 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.
// - outer_size.x <= 0.0f -> Right-align from window/work-rect right-most edge. With -FLT_MIN or 0.0f will align exactly on right-most edge.
// - outer_size.x > 0.0f -> Set 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 -> No minimum height (but will auto extend, unless NoHostExtendV is set)
// - outer_size.y > 0.0f -> Set Minimum height (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 -> No minimum height (but will auto extend, unless _NoHostExtendY is set)
// - 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, 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.
// - 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.
//-----------------------------------------------------------------------------
// Outer size is also affected by the NoHostExtendX/NoHostExtendY flags.
// Important to that note how the two flags have slightly different behaviors!
// - ImGuiTableFlags_NoHostExtendX -> Make outer width auto-fit to columns (overriding outer_size.x value). Only available when ScrollX/ScrollY are disabled and Stretch columns are not used.
// - ImGuiTableFlags_NoHostExtendY -> Make outer height stop exactly at outer_size.y (prevent auto-extending table past the limit). Only available when ScrollX/ScrollY are disabled. Data below the limit will be clipped and not visible.
// 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)
//-----------------------------------------------------------------------------
// About 'inner_width':
// With ScrollX disabled:
// - inner_width -> *ignored*
// With ScrollX enable:
// With ScrollX enabled:
// - inner_width < 0.0f -> *illegal* fit in known width (right align from outer_size.x) <-- weird
// - inner_width = 0.0f -> fit in outer_width: Fixed size columns will take space they need (if avail, otherwise shrink down), Stretch columns becomes Fixed columns.
// - inner_width > 0.0f -> override scrolling width, generally to be larger than outer_size.x. Fixed column take space they need (if avail, otherwise shrink down), Stretch columns share remaining space!
