function Table(table)
for ibody=1, #table.bodies do
local tbody = table.bodies[ibody]
for irow=1, #tbody.body do
local row = tbody.body[irow]
for icell=1, #row.cells do
local cell = row.cells[icell]

for iblock=1, #cell.contents do
cell.contents[iblock] = cell.contents[iblock]:walk(some_filter_map) -- cell blocks can be walk'ed again

I wonder is there a specific reason to exempt the element components like rows and cells from the normal visitor pattern?

I want to modify how table cells are translated. I started out like with other AST types, e.g.

function Cell(cell)
... (do something with cell)
end

This function is never called, although the input document contains a table with cells.

I assume, element components like cells are treated differently (although they seem to appear in the AST like other AST nodes).

What is the correct way to write filter functions for element components?

Thanks, T.
