I would like to create a table with some columns' width specified, while the text in those columns should be centered both horizontally and vertically. I found out that

10.27.2.2 How to change color for a block of texts?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=17104

I am editing a LaTeX paper with Emacs. Sometimes I want to make a block of texts less obvious (or less important to see). Instead of totally hiding them, they should still be there. Is there an easy ...

10.27.2.4 Show equation number only once in align environment

https://tex.stackexchange.com/landing/r/digest?cta=question&id=17528

I want the equation number to be shown only at the last line, or better, somewhere in the middle of all. So instead of (1), (2), ... only (1). 
I use \begin{align} ... \end{align}

10.27.2.5 Underscores in words (text)

https://tex.stackexchange.com/landing/r/digest?cta=question&id=48632

How can I produce the text Word_one_two in LaTeX? 
I tried: 
Samp\_Dist\_Corr 
But, it doesn't quite look right. Also, I want it in the typewriter font, so actually, I'm doing: 
\texttt{Samp\_Dist\...

10.27.2.6 Reduce space between enumerated items

https://tex.stackexchange.com/landing/r/digest?cta=question&id=6081

Background 
All book figures are set to "here definitely" (as they must come after the text that introduces them).

10.27.2.7 How do I put text over symbols?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=74125

This is difficult for me to explain, but how do I put words over a symbol? For instance, I want to add words over an equal sign. Anyone know the command/syntax for that? 
Also adding ^ doesn't cut it.....
