The intersection of horizontal clines and vertical lines in tables look weird. Here is a MWE:

documentclass[11pt,oneside]{article}

%usepackage{array}



begin{document}



begin{table}

centering

begin{tabular}{c|c|c|c}

cline{2-3}

a&b&c&d\

cline{2-3}

end{tabular}  

end{table}



end{document}

Here is the output:

As you can see, there are small gaps at the intersections of the horizontal and the vertical lines at the two corners at the bottom. Interestingly, the two corners at the top are fine.

Now if the array package is loaded (simply uncomment in the code above), then I get:

The weird gap is gone at the lower right corner but it still persists at the lower left corner.

I did a considerable amount of research into this (see, e.g., this post) but did not find any definitive solution. Any suggestions would be greatly appreciated.

(I am aware of the existence of hhline but I read in another post that it might be prone to similar intersection issues, so I’d prefer a solution without it.)

Don't know why it happens, but here's a fix...diminish the \ by arrayrulewidth (EDITED to reflect arrayrulewidth rather than fboxrule, hat tip: David Carlisle).

documentclass[11pt,oneside]{article}

%usepackage{array}

cline{2-3}

a&b&c&d\[-arrayrulewidth]

cline{2-3}

end{tabular}  

end{table}



end{document}

If one is concerned that this approach shrinks the height of the cell by -arrayrulewidth, then just compensate by adding an extra arrayrulewidth to the depth of the line before the shrunken \. Compare the original box on the left with the revised on the right.
