2521+##### Grid Table Limitations #####
2522+
2523+Pandoc does not support grid tables with row spans or column spans.
2524+This means that neither variable numbers of columns across rows nor
2525+variable numbers of rows across columns are supported by Pandoc.
2526+All grid tables must have the same number of columns in each row,
2527+and the same number of rows in each column. For example, the
2528+Docutils [sample grid tables] will not render as expected with
2529+Pandoc.
