okay guys thanks! But still wondering why after 7 years this is not implemented, imean some items are. But very need items like this still need to be done by scripting, thats weird, isnt it???

Its a bit of an old thread but i find it very usefull. I seem some simularities with AS scripting and python or php code.
I kept getting error, probably a format coding error, when the style has a space like his example Resize_Yellow Style_10mm.jsx it will give a error cause the space gets a ASCII code %20 for a space. I change line 2 which looks for %20 and replaces this with a space. The new working code for me on OSX looks like this then.

if (app.activeScript.name.match(/_/g).length == 2) {
cellStyleName = app.activeScript.name.split(‘_’)[1].replace(‘%20’, ” “);
//newHeight = app.activeScript.name.split(‘_’)[2].split(‘.’)[0];
newHeight = app.activeScript.name.split(‘_’)[2].split(‘.jsx’)[0];
if (app.activeDocument.cellStyles.item(cellStyleName).isValid)
app.doScript (sizeRows, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.FAST_ENTIRE_SCRIPT, “Undo Resize Height of “+cellStyleName);
else
alert (‘There is no Cell Style named “‘+cellStyleName+'”‘);
} else
alert (‘The name “‘+app.activeScript.name+'” should be in the format “Resize_CellStyleName_Height.jsx”!’);

function sizeRows (){
cellarray = app.activeDocument.stories.everyItem().tables.everyItem().cells.everyItem().getElements();
for (a=0; a<cellarray.length; a++)
if (cellarray[a].appliedCellStyle.name == cellStyleName)
cellarray[a].height = newHeight;
}

I think i found it i replace +~j to \r, so it look at the paragraph letter??? Seems to work. So now the code is ^.\r|[\w-] this will automatically Sentence Case a Paragraph
