You have a lot of issues in your shown code.




  1. Do you really need all the packages you are loading?

  2. You load several packages twice, do not do this!

  3. Have a closer look at the order of calling packages. In your case package cleveref should be called last. If you want to use hyperref too load it before cleveref!

  4. For the problem with your table the used font is not relevant (I commented it).

  5. The definition for C you used in your table is missing. Because you load array I think newcolumntype{C}[1]{>{centeringarraybackslash}m{#1}} is what you are using but you had not copied into your code. If you use p{#1} instead of my m{#1} please check the added screenshot below for differences!

  6. I did a little bit pretty printing with your table so the reader can faster locate a special cell in the table.

  7. I commented all not needed packages you used in your code for the issue with the table. Please check the different order of loading packages!

  8. Please see that centering is not working with your used class inside environment table. To visualize this I added package showframe. It shows typing area and margins ... The reason is that class IEEEtran uses a two-column-layout. Then environment table has to fit into one column, but your used table exceeds the possible columnwidth. To get rid of this use environment table* instead. It spans both columns ...


  9. I commented tablesize{footnotesize} because it throws the error message comand tablesize undefined.


  10. Your used command bf is outdated, in your case you can use textbf{...} instead (as I did in the following code). An alternative would be to change bf to bfseries.

  11. Because you gave us no bib file I simply commented your citing of books etc. in the table (cite) ...


With the following code

Your code has some serious issues. The fact that the C column type isn't defined is not even the most serious issue.




  • The IEEEtran document class employs a two-column layout by default. You need to employ a table* environment instead of a table environment, so that the tabular material may safely span both columns.


  • Since the table* environment spans both columns, you might as well make use of this fact and employ a tabularx environment instead of a tabular environment. I suggest you use the basic l column type for the left-hand column and the X column type for the next three columns.


  • The caption and subcaption packages are known not be compatible with the IEEEtran document class. Don't load these packages. Instead, just rely on the caption formatting algorithms provided by the IEEEtran document class.


  • Do give the tabular material a more open "look", mainly by using fewer horizontal rules. Also, don't over-use bold-facing. For sure, for the table at hand, using bold-facing for the header cells risks coming across as tacky, maybe even a bit vulgar.


  • As @Kurt has already pointed out in his answer, don't load packages multiple times. In fact, do ask yourself if you really need all the packages you currently load. The code below loads only those packages that are required to make the table compilable.

    • The fact that the caption is not centered over the table should be a give-away that the document class employs two-column mode. Hence, do please inform the OP that he/she should be using a table* environment, to let the material span both columns.

    You have a lot of issues in your shown code.




    1. Do you really need all the packages you are loading?

    2. You load several packages twice, do not do this!

    3. Have a closer look at the order of calling packages. In your case package cleveref should be called last. If you want to use hyperref too load it before cleveref!

    4. For the problem with your table the used font is not relevant (I commented it).

    5. The definition for C you used in your table is missing. Because you load array I think newcolumntype{C}[1]{>{centeringarraybackslash}m{#1}} is what you are using but you had not copied into your code. If you use p{#1} instead of my m{#1} please check the added screenshot below for differences!

    6. I did a little bit pretty printing with your table so the reader can faster locate a special cell in the table.

    7. I commented all not needed packages you used in your code for the issue with the table. Please check the different order of loading packages!

    8. Please see that centering is not working with your used class inside environment table. To visualize this I added package showframe. It shows typing area and margins ... The reason is that class IEEEtran uses a two-column-layout. Then environment table has to fit into one column, but your used table exceeds the possible columnwidth. To get rid of this use environment table* instead. It spans both columns ...


    9. I commented tablesize{footnotesize} because it throws the error message comand tablesize undefined.


    10. Your used command bf is outdated, in your case you can use textbf{...} instead (as I did in the following code). An alternative would be to change bf to bfseries.

    11. Because you gave us no bib file I simply commented your citing of books etc. in the table (cite) ...

    You have a lot of issues in your shown code.




    1. Do you really need all the packages you are loading?

    2. You load several packages twice, do not do this!

    3. Have a closer look at the order of calling packages. In your case package cleveref should be called last. If you want to use hyperref too load it before cleveref!

    4. For the problem with your table the used font is not relevant (I commented it).

    5. The definition for C you used in your table is missing. Because you load array I think newcolumntype{C}[1]{>{centeringarraybackslash}m{#1}} is what you are using but you had not copied into your code. If you use p{#1} instead of my m{#1} please check the added screenshot below for differences!

    6. I did a little bit pretty printing with your table so the reader can faster locate a special cell in the table.

    7. I commented all not needed packages you used in your code for the issue with the table. Please check the different order of loading packages!

    8. Please see that centering is not working with your used class inside environment table. To visualize this I added package showframe. It shows typing area and margins ... The reason is that class IEEEtran uses a two-column-layout. Then environment table has to fit into one column, but your used table exceeds the possible columnwidth. To get rid of this use environment table* instead. It spans both columns ...


    9. I commented tablesize{footnotesize} because it throws the error message comand tablesize undefined.


    10. Your used command bf is outdated, in your case you can use textbf{...} instead (as I did in the following code). An alternative would be to change bf to bfseries.

    11. Because you gave us no bib file I simply commented your citing of books etc. in the table (cite) ...


    With the following code

    Your code has some serious issues. The fact that the C column type isn't defined is not even the most serious issue.




    • The IEEEtran document class employs a two-column layout by default. You need to employ a table* environment instead of a table environment, so that the tabular material may safely span both columns.


    • Since the table* environment spans both columns, you might as well make use of this fact and employ a tabularx environment instead of a tabular environment. I suggest you use the basic l column type for the left-hand column and the X column type for the next three columns.


    • The caption and subcaption packages are known not be compatible with the IEEEtran document class. Don't load these packages. Instead, just rely on the caption formatting algorithms provided by the IEEEtran document class.


    • Do give the tabular material a more open "look", mainly by using fewer horizontal rules. Also, don't over-use bold-facing. For sure, for the table at hand, using bold-facing for the header cells risks coming across as tacky, maybe even a bit vulgar.


    • As @Kurt has already pointed out in his answer, don't load packages multiple times. In fact, do ask yourself if you really need all the packages you currently load. The code below loads only those packages that are required to make the table compilable.
