Superfluous row when using cells with arbitrary `y`

The usage of tablex shown below has the following (unexpected) output, with one more row than necessary:

#tablex(
  columns: 3,
  [a],
  cellx(y: 2)[a]
)

These lines seem to be cause.

Lines 231 to 235 in b3b441f

    
           let is_at_first_column(grid_len) = calc-mod(grid_len, col_len) == 0 
        
           while not is_at_first_column(get-expected-grid-len(items + new_items, col_len: col_len)) {  // fix incomplete rows 
        
               new_items.push(cellx[]) 
        
           }

I might just remove them, as trying to predict the grid length is just an heuristic after all, and having an "incomplete row" is fixed by the last few lines of the grid generator function (which goes over any none items in the grid and replaces them with empty cells).

Fixed in 7780d91.

	let is_at_first_column(grid_len) = calc-mod(grid_len, col_len) == 0

	while not is_at_first_column(get-expected-grid-len(items + new_items, col_len: col_len)) { // fix incomplete rows
	new_items.push(cellx[])
	}
