This is the old version of tables, that now is called `SimpleTable`, see
https://pandoc.org/lua-filters.html#type-simpletable

You can use the same syntax with current pandoc this way:

```lua
t = pandoc.SimpleTable( {}, { "AlignDefault" }, {}, { {} }, { { { elem }
} } )
```

and then convert it to a Table with:

```lua
t2 = pandoc.utils.from_simple_table(t)
```

By the way, I noticed that there's no `pandoc.TableBody` constructor.

The only way I found is through a lua table like this:

```lua
body = {
attr = pandoc.Attr(),
head = {},
row_head_columns = 0,
body = { pandoc.Row( { pandoc.Cell( { elem } ) } ) }
}
```

So a minimal table is made like this:

```lua
t = pandoc.Table(
{}, -- empty caption
{ { 'AlignDefault', 0 } }, -- one column, default alignment and width
pandoc.TableHead(), -- empty table head
{ body }, -- a list of one body
pandoc.TableFoot() -- empty table foot
)
```
