### Upcoming Changes
Some of the goals for 2020 are:
- Work on Tables (see [#2957](https://github.com/ocornut/imgui/issues/2957), now merged in master.
Some of the goals for 2021 are:
- Work on Docking (see [#2109](https://github.com/ocornut/imgui/issues/2109), in public [docking](https://github.com/ocornut/imgui/tree/docking) branch)
- Work on Multi-Viewport / Multiple OS windows. (see [#1542](https://github.com/ocornut/imgui/issues/1542), in public [docking](https://github.com/ocornut/imgui/tree/docking) branch looking for feedback)
- Work on gamepad/keyboard controls. (see [#787](https://github.com/ocornut/imgui/issues/787))

// Note that stb_sprintf.h is meant to be provided by the user and available in the include path at compile time. Also, the compatibility checks of the arguments and formats done by clang and GCC will be disabled in order to support the extra formats provided by STB sprintf.

// - 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)
// - 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!
// Override declared contents width to enable auto-resize on the X axis when possible.
// FIXME-TABLE: This can be improved (e.g. for Fixed columns we don't want to auto AutoFitWidth? or propagate window auto-fit to table?)
