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?

    Welcome to TeX.SE! column 8 is to wide because text "Percentage of Clusters removed by" is to wide and consequently expand width of last column over which it is span. A question: does you really need long table (is table more page long)?

  • Yes @Zarko the table is more than one page long. Sometimes the table spans more than 3 pages as well. But I am unable to find the solution from your description. Is it really possible to fix the width for the statement "Percentage of Clusters removed by".

I would like to suggest that you streamline and simplify much of the code in the longtable environment. I would also like to suggest that you not use boldface at all; it's not needed -- really. Double vertical lines aren't needed either.

Maybe you will like this more professional looks of table

Note: your basic problem can be solved on two ways:

  • broke text in \multicolumn{4}{c}{Percentage of Clusters removed by} into two line, that the width of multicolumn is smaller than sum of spanned columns widths and preserve your column definitions
  • or change column definition as suggested Mico and it is further elaborate in this answer

  • Thanks @Zarko your description is also a solution to my problem. But I would appreciate if you can give some hint on which table environment is better for such tables. Always the limitation of one environment forces me to use some other. So I have to switch between different environments.

  • @OptimistOptimizer, LaTeX provide many table environments, each is dedicated to specific problem. In above case the tabularx is the best solution (to my opinion) because: (i) it itself calculate column width, (ii) has prescribed width, (iii) columns are of paragraph type (not very relevant for this table). I believe, that stick with two table environments (tabular and tabularx) in your document and also switch from one to other, is not big deal :). In this case you need only to change tabular to tabularx, determine table width and that that is.

  • OK. I have another difficulty that your provided solution does not work if I use <vpos> ([b]) for multirow. So I have to remove all [b] in the above provided solution for a successful compilation. I suspect that I need some extra package for this.

  • @OptimistOptimizer, it seems that you have old version of ˙multirow` packages. I strongly encourage you to upgrade your LaTeX installation to the recent version.
