I am a beginner in LaTeX and have to make some very sophisticated tables in it. I use help from TeX.SE to complete the jobs of drawing these difficult tables.
This time I have been stuck with a table: Everything is working fine except a column (no. 8) is too wide. I have tried some tricks but nothing worked this time. Can anybody please help me to fix this problem?
