Graphics, Figures & Tables ⇒ Help with width adjustment for table using multicolumn.

[ankitravankar]

Hi,

I need help with the column width adjustment for my table. The table looks too constrained. I want the text to have spaces between the lines. The text is not centered and also the lines are not aligned properly for this table. Can someone help me and teach on how to adjust width when using \multicolumn. I am using this table on a two column article.
Thanks

I don't know your actual setup, please provide a minimum working example next time.

There are many Values in just one line, i don't know if there might be mor rows. But here is a counter proposal using booktabs:
