Re: Define "Complex Data Table"

Multiple header rows or columns are not a problem. The algorithm is 
given in the HTML 4.01 Specification [1]. It says "search left from the 
cell's position to find row header cells. Then search upwards to find 
column header cells. The search in a given direction stops when the edge 
of the table is reached or when a data cell is found after a header 
cell." A complex table is one for which this doesn't work, such as when 
  header cells are in a different row or column. The recommendation 
doesn't seem to define what a complex table is (it doesn't use that 
term) but provides an example and illustrates what the problem is.
