Thank you Stefan.I hope to make use of this forum the most and if possible contribute something from my own side.

Hi,

I am a beginner with LaTeX and have a doubt. I am writing code for creating a table. The question is I want to have the horizontal lines of the table in blue color. The lines that separate the rows (\hline). How can I make it in some color?

I tried \color{blue}{\hline} but it's not working ...
