// When ScrollX is on:
// - Table defaults to ImGuiTableFlags_SizingPolicyFixedX -> all Columns defaults to ImGuiTableColumnFlags_WidthFixed.
// - Columns sizing policy allowed: Fixed/Auto mostly! Using Stretch columns OFTEN DOES NOT MAKE SENSE if ScrollX is on, UNLESS you have specified a value for 'inner_width' in BeginTable().
// - Fixed Columns can be enlarged as needed. Table will show an horizontal scrollbar if needed.
// - Stretch Columns, if any, will calculate their width using inner_width, assuming no scrolling (it really doesn't make sense to do otherwise).
// - Fixed Columns can be enlarged as needed. Table will show an horizontal scrollbar if needed.
// - Stretch Columns, if any, will calculate their width using inner_width, assuming no scrolling (it really doesn't make sense to do otherwise).
// - Mixing up columns with different sizing policy is possible BUT can be tricky and has some side-effects and restrictions.
// (their visible order and the scrolling state have subtle but necessary effects on how they can be manually resized).
// The typical use of mixing sizing policies is to have ScrollX disabled, one or two Stretch Column and many Fixed Columns.
