table, table.row and table.cell start at column 2, should be column 1

As observed in the running code, and also show in the AST docs the position attribute of table elements ignores the initial vertical bar '|' showing position.start.column as '2'. This is different than other elements such as headers, blocks and lists which all start at column 1 and include all the markup characters.

I think for consistency tables should start at the first table '|' character counted inclusively. Thanks.

Agreed.
