Hi scilab Team, i have experimented with tables and prettyprint. and have seen, that scilab lates not recognizes table. Would be this not be a nice feature for upcomming milestone?  
An i also have seen, that when you launch JCEF, the whole scilab gui changes to JCEF mode by so.

Hello Pascal,

Did you have a look to the following post (don’t pay attention to the title, it is about LaTeX export of tables): [Export a table to a file - #3 by mottelet](https://scilab.discourse.group/t/export-a-table-to-a-file/855/3) ? You should be able to reuse the code to generate LaTeX markup for an arbitrary table.

sorry, no, i did not seen it, it is also a possibility and feasibility, but not so elegant.  
And for the other point, has someone noticed?

Do you have a more elegant solution 🤣? Moreover, if the feature has to be coded in `prettyprint()` I am affraid that the code will be very similar. Missing features have to be coded, that’s the law !

Yeah, but as lazy enduser, it would be nice that table can by simple prettyprint be in Latex 🙂

Can you test the following code:

```auto
function str = table2latex(t)
    [_,m] = size(t);
    head = strcat(t.props.VariableNames," & ") + " \\ "
    data = strcat(strcat(string(t)," & ","c")," \\ ")
    str = [ sprintf("\\begin{tabular}{%s}",strcat("r"(ones(1,m)),"|"))
        head; "\hline"; data; "\end{tabular}" ];
    str = strcat(str," ");
endfunction

```

after defining the function `table2latex`, the Scilab function `prettyprint` should work for tables (default LateX mode):

```auto
t = table(rand(5,3,"normal"), ...
    "VariableNames",["var1Name","var2Name","myLongVarName"])
pp = prettyprint(t)
titlepage(pp)
gce().interpreter = "latex"

```

The box is made by `titlepage`, use the latex code as you want…

doesn’t quite work on every occasion, must look why. maybe because my table are full in string or struct2table is not quite the same as table?

i have seen, that discourse mismatches the “” scilab string function.

Please use code blocks, otherwise this is very complicated to copy-paste the code you are posting (see [https://scilab.discourse.group/t/welcome-to-the-scilab-discourse-forum](https://scilab.discourse.group/t/welcome-to-the-scilab-discourse-forum)).

Likely, you didn’t understand the different mechanisms in place: you don’t have to call yourself `table2latex` (it is automatically called by `prettyprint`). So the whole code of your example should be:

```auto
function str = table2latex(t)
    [_,m] = size(t);
    head = strcat(t.props.VariableNames," & ") + " \\ "
    data = strcat(strcat(string(t)," & ","c")," \\ ")
    str = [ sprintf("\\begin{tabular}{%s}",strcat("r"(ones(1,m)),"|"))
        head; "\hline"; data; "\end{tabular}" ];
    str = strcat(str," ");
endfunction

Table_WI=struct2table(WI);

pp = prettyprint(Table_WI)
titlepage(pp)
gce().interpreter = "latex"

```

The alignment of strings within the columns can be changed, e.g. if you want to center strings just change `"r"` line 6 of `table2latex` by `"c"` (center) or `"l"` (left).

Thanks, yes this works. Although the spaces between are not, but i can work around it. many thanks. 🙂

You can tune almost everything from the LaTeX side.
