/**
* Visit tables.
*
* The RST table rendering algorithm tries losely to fit a table in the
* provided document dimensions. This may not always work for over long words,
* or if the table cells contain literal blocks which can not be wrapped.
*
* For this the algorithm estiamtes the available width per column, equally
* distributes this available width over all columns (which might be far from
* optimal), and extends the total table width if some cell content exceeds the
* column width.
*
* The initial table cell estiation happens inside the function
* estimateColumnWidths() which you might want to extend to fit your needs
* better.
