Table's cells + GREP/Regex + diagonal lines

I want here ot thanks all of you for the quality of your answers and feeback! This is great to see this!

You'll need a script for this, you won't be able to do it in the interface (not reasonably, anyway). The script gets all the empty texts/stories using the GREP expression that you already use, then it cycles through them and applies a cell style to the cells that contain those empty strings. The cell style, which sets the diagonal line, as Uwe mentions, should be present. Here goes:

app.findGrepPreferences = null;
app.findGrepPreferences.findWhat = '^\\Z';
cellStyle = app.documents[0].cellStyles.item ('diagonalLine');
empties = app.documents[0].findGrep();
for (i = 0; i < empties.length; i++) {
  if (empties[i].parent instanceof Cell) {
    empties[i].parent.appliedCellStyle = cellStyle;
  }
}

Hi @jeromevadon ,

don't know how exactly you'll define an empty cell, but if you only aim at empty text cells, you could ask for its contents value. If that is an empty string, you could use all the properties for diagonalLine to draw one. Or apply a cell style that has the diagonal line defined in the manner you need it.

Basically it's this when a cell is selected and a cell style with name "diagonalLine" is defined:

var myCell = app.selection[0];
var digonalLineCellStyle = app.documents[0].cellStyles.itemByName("digonalLine");

if ( myCell.contents == "" )
{ myCell.appliedCellStyle = digonalLineCellStyle };
