(#2957, #125) + Check out 'Demo->Tables' for many demos + API comments in imgui.h for details. + - Added 16 functions: BeginTable(), EndTable(), + TableNextRow(), TableNextColumn(), TableSetColumnIndex(), TableGetColumnIndex(), TableGetRowIndex(), + TableSetupColumn(), TableSetupScrollFreeze(), + TableHeadersRow(), TableHeader(), TableSetBgColor(), TableGetSortSpecs(), + TableGetColumnCount(), TableGetColumnName(), TableGetColumnFlags(). + - Added 2 structures: ImGuiTableSortSpecs, ImGuiTableColumnSortSpecs. + - Added 2 enums: ImGuiSortDirection, ImGuiTableBgTarget. + - Added 3 flags sets: ImGuiTableFlags (27 flags), ImGuiTableColumnFlags (24 flags), ImGuiTableRowFlags (1 flags). + - Added 5 colors: ImGuiCol_TableHeaderBg, ImGuiCol_TableBorderStrong, ImGuiCol_TableBorderLight, ImGuiCol_TableRowBg, ImGuiCol_TableRowBgAlt. + - Added 1 style var: ImGuiStyleVar_CellPadding. - Tab Bar: Made it possible to append to an existing tab bar by calling BeginTabBar()/EndTabBar() again. - Tab Bar: Fixed using more than 128 tabs in a tab bar (scrolling policy recommended). - Tab Bar: Do not display a tooltip if the name already fits over a given tab.
