// - Columns can either varying resizing policy: "Fixed", "Stretch" or "AlwaysAutoResize". Toggling ScrollX needs to alter default sizing policy.
// - Sizing policy have many subtle side effects which may be hard to fully comprehend at first.. They'll eventually make sense.
// - with SizingPolicyFixedX (default is ScrollX is on): Columns can be enlarged as needed. Enable scrollbar if ScrollX is enabled, otherwise extend parent window's contents rect. Only Fixed columns allowed. Weighted columns will calculate their width assuming no scrolling.
// - with SizingPolicyStretchX (default is ScrollX is off): Fit all columns within available table width (so it doesn't make sense to use ScrollX with Stretch columns!). Fixed and Weighted columns allowed.
// - Important! Sizing policies have particularly complex and subtle side effects, more so than you would expect.
// Read comments/demos carefully + experiment with live demos to get acquainted with them.
// - The default sizing policy for columns depends on whether the ScrollX flag is set on the table:
// When ScrollX is off:
// - Table defaults to ImGuiTableFlags_SizingPolicyStretchX -> all Columns defaults to ImGuiTableColumnFlags_WidthStretch.
// - Columns sizing policy allowed: Fixed/Auto or Stretch.
// - Stretch Columns will share the width available in table.
// - Fixed Columns will generally obtain their requested width unless the Table cannot fit them all.
// 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).
// - 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.
