@percusse What is the big confusion about .store in and .get?

@remjg In the evening, I'll take another look. As Qrr mentioned, this is far from a satisfactory answer and needs some under the hood demo. Where is Ryan Reich when you need him? — percusse 12 hours ago

A: Using \phantom in subscript with the bayesnet TikZ library

Yes, you can measure the width. With \sbox0{$\scriptstyle N-$} and one \hspace*{.5\wd0} before and after the actual content would solve this. But it is easier to use the text width key (or minimum width subtracting the /pgf/inner xsep values). You can use either \widthof (more robust) or P...

any one knows how to make a horizontal line in multicols, that only span the column and not across the whole page? I use \hrule but the line go across the 3 columns. I only want it to go one column ofcourse

\begin{multicols}{3}
...
\hrule
....
\end{multicols}

Qrrbrbirlbel

@Nasser Shouldn’t \hrule have some parameters (width, height, depth)? Anyhow, have you tried \hrulefill?

Nasser

@Qrrbrbirlbel , yes I tried \hrulefill. The problem I do not know the width to use. For pdf, I can guess, but I am also compling with tex4ht to HTML. I thought this is automated, so that it can calculate the width itself?

\hrulefill does not work, even in PDF. The line goes across the whole page

hhh

How can I create two lines for sum $\sum_{oneLine \\ SecondLine}$?

Qrrbrbirlbel

@Nasser Hm, can you try \noindent\hrule width\linewidth\relax?

@hhh \sum_{\substack{oneLine \\ secondLine}} (amsmath)

@Qrrbrbirlbel Thank you, worked like a charm!

Do I need to import some pkg for \hspace{3} command like $\sum_i p(i) \hspace{10}\forall p\in P$?

(I try to add spaces between the equation an the quantifiers but now they are written immediately after one another, hard reading)

Qrrbrbirlbel

@hhh You need a unit … otherwise LaTeX provides shortcut for common lengths: \,, \:, \;, \quad, \qquad which are usually used

Nasser

@Qrrbrbirlbel sorry I did not hear the beep. How to turn it on? Will try now!

\begin{equation}\label{eq:FV}
\begin{split}
e_1\succ_{FV} e_2 &\Leftrightarrow Q\left(p|e_2^c\right) \geq Q\left(p|e_1^c\right) \\
&\Leftrightarrow \sum_{\substack{i=1 \\ e_1\in C_i, e_2\not\in C_i}}^{N_{cut}} \prod_{j\in C_i} p_j - \sum_{\substack{i=1 \\ e_2\in C_i, e_1\not\in C_i}}^{N_{cut}} \prod_{j\in C_i} p_j \geq 0 \hspace{1\;} \forall p\in P_F
\end{split}
\end{equation}

I am getting some error due to the split environment

when I add the \hspace{1\;}, it started to fire err there.

Qrrbrbirlbel

@hhh Oh no. Those commands I recited do actually insert space. They are not a unit! Units are pt, mm, in and mu, ex and em.

hhh

?

Do I need \hspace at all?

Qrrbrbirlbel

The mu is an eigthteenth of an em (those and ex are font related units).

Nasser

@Qrrbrbirlbel thanks. THis worked \noindent\hrule width\linewidth\relax BUT only for pdf. When I generated the HTML with tex4ht, the line was going across the whole web page. I guess tex4ht does not support this. oh well. Thanks for your help.

Qrrbrbirlbel

No either \hspace{<number><unit>} like \hspace{0.5em} or \; (which do an internal version of \hspace on their own).

hhh

5:55 AM

I see -- \quad worked like a charm alone, thank you again :)

Qrrbrbirlbel

@Nasser I don't know about tex4ht. Isn't there a HTML equivalent of lines?

Nasser

@Qrrbrbirlbel I am sure there is, if I hack it and insert direct HTML commands, but I really do not need to do this...

How to make \hline a dashed line?

Q: Can a table include a horizontal dashed line?

In a normal table, you can use the \hline command to draw a horizontal line. I am trying to make this line a dashed horizontal line. I have found the package dashrule via this answer, but this only works for \rule situations; i.e. it can't be directly used as a line in a table, and LaTeX won't c...

Solved.
