box, strut

box, strut

[Patrick Gundlach]

Hello,

could someone please explain the following result?

\starttext
\setbox0=\hbox{fg}\showbox0 
\setbox0=\hbox{\strut fg}\showbox0 
\stoptext

gives

> \box0=
\hbox(8.33331+2.33331)x9.46518
./cmr12/f
./cmr12/g

! OK.
l.3 \setbox0=\hbox{fg}\showbox0
                               

> \box0=
\hbox(10.41603+4.05064)x9.46518
.\hbox(10.41603+4.05064)x0.0
..\rule(10.41603+4.05064)x0.0
..\glue 0.0 plus 1.0fil minus 1.0fil
./cmr12/f
./cmr12/g

! OK.
l.4 \setbox0=\hbox{\strut fg}\showbox0



OK, the first box is easy. The second one gives me a slight headache:
why is the rule 10.4 + 4.1 pt? (14.46667 total)

the definition of strut(box) is 

 \setbox\strutbox=\hbox{\vrule height8.5pt depth3.5pt width\z@}

so where do the other 2.46667 point come from?

in context the strut (box) is defined in a non fixed way, i.e. it adapts 
itself to the font settings; your def is the plaintex def

grep core-spa.tex for 'strut' (there are actually different kind of struts 
and you can define your own)

Extending into the left margin

[Duncan Hothersall]

Hi all.

I'm using the nice \bTABLE natural tables commands to set my tables. I'm 
now running into tables which need a little extra space, and since I 
have a wide left margin I would like them to extend into it. By default 
they extend into the right marging, which doesn't have very much space 
and looks ugly.

Because I'm using [split=yes] to enable tables to split over pages, I 
don't want to just put the whole table in a box and then shift it to the 
left. I am wondering if I can use a localised setuplayout to change the 
left margin just for the duration of the table? Or is there another 
clean way to get specific tables to extend into the left margin?

Many thanks.
