// 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.
// - Table defaults to ImGuiTableFlags_ColumnsWidthStretch -> all Columns defaults to ImGuiTableColumnFlags_WidthStretch.
// - Columns sizing policy allowed: Stretch (default) or Fixed/Auto.
// - 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.
// - Table defaults to ImGuiTableFlags_ColumnsWidthFixed -> all Columns defaults to ImGuiTableColumnFlags_WidthFixed.
// - Columns sizing policy allowed: Fixed/Auto mostly!
// - Fixed Columns can be enlarged as needed. Table will show an horizontal scrollbar if needed.
// - Using Stretch columns OFTEN DOES NOT MAKE SENSE if ScrollX is on, UNLESS you have specified a value for 'inner_width' in BeginTable().
