Hi everyone,

Excuse my poor English. I recently updated my online table generator 
(http://latex-tables.com) to support ConTeXt. It also supports many 
languages, like LaTeX, Plain TeX, Markdown, HTML and more. It uses the 
eXtreme table format and supports many features including :


- Borders, border width and border color

- Merged cells

- Background color

- Alignment (flushleft, center, flushright)

- Splitted tables

- Rotated tables

- Caption

- More...

However, I have many issues that I have trouble to fix.

1/ I have many troubles with borders, because I can't set the color 
and the width of each border. Instead, I use "fake rows" and "fake 
cells" when it is necessary. However, I can't figure out how to set 
the height of a row to 0.4pt. It's always bigger. So, instead I use 
"location=hanging" on this row but, because of this, borders are 
hidden behind the next row's background. What can I do about this ?




Frames accept only a single color and line thickness for all borders but 
there are two ways to set different values for each side The first 
method is to disable the frame and apply a background graphic where you 
draw different lines for each side. The other method is to create a 
custom renderer for each frame (top, bottom etc.) where you can than 
apply a different color or linewidth for each side, below (and also 
attached) is a example where I show how this can be done.

[NTG-context] Table generator : Issues with borders and rotated cells

2018-06-19 Thread Xavier Dionne 
Hi everyone,

Excuse my poor English. I recently updated my online table generator 
(http://latex-tables.com) to support ConTeXt. It also supports many languages, 
like LaTeX, Plain TeX, Markdown, HTML and more. It uses the eXtreme table 
format and supports many features including :

- Merged cells
- Background color
- Alignment (flushleft, center, flushright)
- Splitted tables
- Rotated tables
- Caption
- More...

However, I have many issues that I have trouble to fix.

1/ I have many troubles with borders, because I can't set the color and the 
width of each border. Instead, I use "fake rows" and "fake cells" when it is 
necessary. However, I can't figure out how to set the height of a row to 0.4pt. 
It's always bigger. So, instead I use "location=hanging" on this row but, 
because of this, borders are hidden behind the next row's background. What can 
I do about this ?

MWE without background color :

\definecolor[Siren][r=0.502,g=0,b=0.251]
\definecolor[Rose][r=1,g=0,b=0.502]
\definecolor[FlushOrange][r=1,g=0.502,b=0]
\definecolor[ElectricViolet][r=0.502,g=0,b=1]
\definecolor[Chartreuse][r=0.502,g=1,b=0]
\definecolor[BlushPink][r=1,g=0.502,b=1]
\placetable[none]{}{
  \startxtable[align=lohi,framecolor=Siren,frame=off,leftframe=on,rightframe=on]
\startxrow[offset=overlay,location=hanging,topframe=on]
  \startxcell\stopxcell
  \startxcell[framecolor=Rose]\stopxcell
\stopxrow
\startxrow
  \startxcell[rightframe=off,framecolor=cyan] A\stopxcell
  \startxcell[rightframe=off,framecolor=FlushOrange] B\stopxcell
  \startxcell[width=0pt,framecolor=ElectricViolet]\stopxcell
\stopxrow

\startxrow[offset=overlay,location=hanging,topframe=on,framecolor=Chartreuse]
  \startxcell\stopxcell
  \startxcell[framecolor=BlushPink]\stopxcell
\stopxrow
  \stopxtable
}

MWE with background color

\definecolor[Siren][r=0.502,g=0,b=0.251]
\definecolor[Rose][r=1,g=0,b=0.502]
\definecolor[FlushOrange][r=1,g=0.502,b=0]
\definecolor[ElectricViolet][r=0.502,g=0,b=1]
\definecolor[Chartreuse][r=0.502,g=1,b=0]
\definecolor[BlushPink][r=1,g=0.502,b=1]
\definecolor[Dolly][r=1,g=1,b=0.502]
\placetable[none]{}{
  
\startxtable[align=lohi,background=color,backgroundcolor=Dolly,framecolor=Siren,frame=off,leftframe=on,rightframe=on]
\startxrow[offset=overlay,location=hanging,topframe=on,background=none]
  \startxcell\stopxcell
  \startxcell[framecolor=Rose]\stopxcell
\stopxrow
\startxrow
  \startxcell[rightframe=off,framecolor=cyan] A\stopxcell
  \startxcell[rightframe=off,framecolor=FlushOrange] B\stopxcell
  \startxcell[width=0pt,framecolor=ElectricViolet]\stopxcell
\stopxrow

\startxrow[offset=overlay,location=hanging,topframe=on,framecolor=Chartreuse]
  \startxcell\stopxcell
  \startxcell[framecolor=BlushPink]\stopxcell
\stopxrow
  \stopxtable
}

2/ I have trouble with rotated cells. It seems to affect the width of the 
table. How can I use a rotated cell without setting manually a fixed width.

MWE :

\placetable[none]{}{
  \startxtable[align=lohi]
\startxrow
  \startxcell \rotate[rotation=90]{Test test test}\stopxcell
  \startxcell Test\stopxcell
\stopxrow
\startxrow
  \startxcell Test\stopxcell
  \startxcell Test\stopxcell
\stopxrow
  \stopxtable
}

Thank you !
