I am trying to use ImGui::ComboAutoSelect() element within a table cell. What I want to achieve is that the combo box auto-resizes to fit the preview text and the table column resizes to fit the size of that combo box. I assume this is what ImGuiComboFlags_WidthFitPreview does, at least at the combo level.
Issue 1:
The behaviour I am seeing instead is that the combo sizes proportionally to around 70% of the column width. If I stretch the column width, the combo box width also changes.
The table has ImGuiTableFlags_NoSavedSettings.
I tried setting SetNextItemWidth to -1 before the ComboAutoSelect call. What this did was stretch the combo infinitely. If I set next item width to constant, the combo doesn't auto-stretch to fit the preview.
Issue 2:
In no case does the table column auto-resize to fit the content. I guess this is not default behaviour, but is there a flag or a call I can use to have it mimick the "Size All Columns To Fit" menu option?
Issue 3:
How do I remove ALL padding from the table cell so that the combo rectangle sits tightly along the table grid lines. I tried setting ImGui::PushStyleVar(ImGuiStyleVar_CellPadding, { 0,0 }) but that didn't work.
Thanks.

See Demo->Tables->Item Width.
(or more generally Demo->Layout & Scrolling->Widgets Width)
TL;DR; you can use ImGui::SetNextItemWidth(-FLT_MIN) to right align framed items. Or ImGui::PushItemWidth(-FLT_MIN); ... ImGui::PopItemWidth() if you want the state to be reused for a several widgets. This is common for framed widgets and makes sense if you use hidden label (given the absence of code I am assuming you are).

Define "fit the content" ? Do you mean fit so the combo width would fit exactly the preview text? In this case, it means that changing the combo selection would resize the table, which seems bizarre. It seems to make sense that the contents of previewed label doesn't feed back into ideal width width.
(It generally depends how the widgets in question reports its ideal size. Since I don't know what ComboAutoSelect() i am assuming it work like a regular BeginCombo)
