+;;; Commentary:
+;;;
+;;; This module provides utility functions to operate on `table' ASTs. It is
+;;; partly based on code from Scribe 1.1a.
+;;;
+;;; Code:
+
+(fluid-set! current-reader %skribilo-module-reader)
+
+
+(define (table-column-count t)
+ ;; Return the number of columns contained in table T.
+ (define (row-columns row)
+ (let loop ((cells (markup-body row))
+ (nbcols 0))
+ (if (null? cells)
+ nbcols
+ (loop (cdr cells)
+ (+ nbcols (markup-option (car cells) :colspan))))))
+
+ (let loop ((rows (markup-body t))
+ (nbcols 0))
+ (if (null? rows)
+ nbcols
+ (loop (cdr rows)
+ (max (row-columns (car rows)) nbcols)))))
