### 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))
//---- Unless IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS is defined, use the much faster STB sprintf library implementation of vsnprintf instead of the one from the default C library.
// 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.
//---- Use stb_printf's faster implementation of vsnprintf instead of the one from libc (unless IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS is defined)
// Requires 'stb_sprintf.h' to be available in the include path. Compatibility checks of arguments and formats done by clang and GCC will be disabled in order to support the extra formats provided by STB sprintf.
// #define IMGUI_USE_STB_SPRINTF
//---- Define constructor and implicit cast operators to convert back<>forth between your math types and ImVec2/ImVec4.
// (Integer encoded as XYYZZ for use in #if preprocessor conditionals. Work in progress versions typically starts at XYY99 then bounce up to XYY00, XYY01 etc. when release tagging happens)
IMGUI_APIvoidEndTable();// only call EndTable() if BeginTable() returns true!
IMGUI_APIvoidTableNextRow(ImGuiTableRowFlagsrow_flags=0,floatmin_row_height=0.0f);// append into the first cell of a new row.
IMGUI_APIboolTableNextColumn();// append into the next column (or first column of next row if currently in last column). Return true when column is visible.
IMGUI_APIboolTableSetColumnIndex(intcolumn_n);// append into the specified column. Return true when column is visible.
// Tables: Headers & Columns declaration
// - Use TableSetupColumn() to specify label, resizing policy, default width/weight, id, various other flags etc.
// Important: this will not display anything! The name passed to TableSetupColumn() is used by TableHeadersRow() and context-menus.
// - Use TableHeadersRow() to create a row and automatically submit a TableHeader() for each column.
// Headers are required to perform: reordering, sorting, and opening the context menu (but context menu can also be available in columns body using ImGuiTableFlags_ContextMenuInBody).
// - You may manually submit headers using TableNextRow() + TableHeader() calls, but this is only useful in some advanced cases (e.g. adding custom widgets in header row).
// - Use TableSetupScrollFreeze() to lock columns (from the right) or rows (from the top) so they stay visible when scrolled.
// - Use TableHeadersRow() to create a header row and automatically submit a TableHeader() for each column.
// Headers are required to perform: reordering, sorting, and opening the context menu.
// The context menu can also be made available in columns body using ImGuiTableFlags_ContextMenuInBody.
// - You may manually submit headers using TableNextRow() + TableHeader() calls, but this is only useful in
// some advanced use cases (e.g. adding custom widgets in header row).
// - Use TableSetupScrollFreeze() to lock columns/rows so they stay visible when scrolled.
IMGUI_APIvoidTableSetupScrollFreeze(intcols,introws);// lock columns/rows so they stay visible when scrolled.
IMGUI_APIvoidTableHeadersRow();// submit all headers cells based on data provided to TableSetupColumn() + submit context menu
IMGUI_APIvoidTableHeader(constchar*label);// submit one header cell manually (rarely used)
// Tables: Sorting
// - Call TableGetSortSpecs() to retrieve latest sort specs for the table. NULL when not sorting.
// - When 'SpecsDirty == true' you should sort your data. It will be true when sorting specs have changed
// since last call, or the first time. Make sure to set 'SpecsDirty = false' after sorting, else you may
// wastefully sort your data every frame!
// - Lifetime: don't hold on this pointer over multiple frames or past any subsequent call to BeginTable().
IMGUI_APIImGuiTableSortSpecs*TableGetSortSpecs();// get latest sort specs for the table (NULL if not sorting).
// Tables: Miscellaneous functions
// - Most functions taking 'int column_n' treat the default value of -1 as the same as passing the current column index
// - Sorting: call TableGetSortSpecs() to retrieve latest sort specs for the table. Return value will be NULL if no sorting.
// When 'SpecsDirty == true' you should sort your data. It will be true when sorting specs have changed since last call, or the first time.

IMGUI_APIintTableGetColumnCount();// return number of columns (value passed to BeginTable)
IMGUI_APIintTableGetColumnIndex();// return current column index.
IMGUI_APIintTableGetRowIndex();// return current row index.
IMGUI_APIconstchar*TableGetColumnName(intcolumn_n=-1);// return "" if column didn't have a name declared by TableSetupColumn(). Pass -1 to use current column.
IMGUI_APIImGuiTableColumnFlagsTableGetColumnFlags(intcolumn_n=-1);// return column flags so you can query their Enabled/Visible/Sorted/Hovered status flags. Pass -1 to use current column.
IMGUI_APIImGuiTableSortSpecs*TableGetSortSpecs();// get latest sort specs for the table (NULL if not sorting).
IMGUI_APIvoidTableSetBgColor(ImGuiTableBgTargettarget,ImU32color,intcolumn_n=-1);// change the color of a cell, row, or column. See ImGuiTableBgTarget_ flags for details.
// Legacy Columns API (2020: prefer using Tables!)
