Your table does not have headings. It is not really a table. The author of the page used tables for layout.
However, you can still extract the information you need. It's just that the niceties HTML::TableExtract will not be available when the table is laid out for visual formatting rather than being a tabular display of data.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
