Tesseract is probably getting confused by the indents for the entries. It 
should be pretty easy to identify the columns using image processing (.e.g. 
create a histogram of black pixel counts for each vertical pixel column). 
Why not just do the page segmentation yourself and pass the three columns 
to Tesseract separately.
