Border collapse not working in simple HTML table

Question

Not sure why but border-collapse is not working in my simple HTML table even after I use border-collapse: collapse. Here's the JS fiddle: http://jsfiddle.net/y5ghL230/

Can somebody help, please?

Answer 1

border-collapse has to be defined for table, see my fiddle:

table {border-collapse: collapse}
