+/// Creates a two-column "function" table with a caption.
+///
+/// Intended for "Funkciju sadalījums moduļos" section
+///
+/// Parameters:
+/// - caption: optional caption; defaults to the first positional item.
+/// - title: tuple of column/section titles (defaults provided).
+/// - items: positional cells; first two items populate the top row,
+///   remaining items are paired with the titles ["Apraksts", "Ievade", ...]
+///
+/// Behavior:
+/// - Renders the first two titles as table headers and the first two
+///   positional items beneath them.
+/// - For titles from index 2 onward, each title is rendered as a full-width
+///   (colspan 2) bold row followed by a full-width row containing the
+///   corresponding positional item. Missing items become empty strings.
+/// - Safe for fewer/more items: missing values are coerced to "", extra
+///   items beyond the paired section are ignored.
+///
+/// Default caption to the first positional item if none provided.
