/**
 * Builds a 2D path table for a single pinned section (start, center, or end). Each row in the
 * output corresponds to a depth level in the column group hierarchy, and each cell is either a
 * group header spanning one or more columns or a leaf cell representing an individual column.
 *
 * maxDepth should reflect the maximum group nesting depth across all sections so that row counts
 * are normalized. When lastGroupShouldFill is true, the last group header for a column extends
 * downward to fill the gap to the leaf row, preventing layout shifts as groups are collapsed or
 * expanded. seenMap is shared across multiple sections in the same render pass to ensure group
 * cell IDs are globally unique. colOffset positions the section's cells within the overall grid.
