Edit All Cells In All Tables

Question

Hello,
This is my first post, but I have been working with InDesign scripting for a while, and am pretty fluent in Javascript.
My scenario is, I have a document with about 1,000 pages. On each page is a table with approximately 100 cells, 10 rows and 10 columns with a description at the 0-space of each, followed by a floating point number (in the form of a percentage) in every other cell. What I need to do is format the text color of each percentage in each row depending on its value. For instance, in the first row, every percentage under 80.00% is red, while everything else needs to be green. All I need to do is color them based on their value. However, this value changes throughout the course of the 10 different rows.
I was able to make a script that would allow me to go over each cell in row 1 of every table on a single page, then iterate over all the other remaining pages in the same way before continuning onto row 2. This is a VERY long process, typically leading to a crash in any document over ~30 pages in length. Given that I want to run this over a gigantic 1,000+ page document (granted there is only 1 table per page), it becomes slightly impractical...
I'm simply curious if there is a way to run this in a more realistic manner. There has to be a quick way to iterate over each row, simply check the values, mark green or red and be done with it. My idea was to, perhaps, do every row in the table on one page and then go onto the next page, as opposed to row 1 over the entire document, followed by row 2, and so on and so forth? Perhaps that would help?
The code is FARRR too long to post here, but the rough process I have right now is the following:
1.) Setup variables to define the cells in each row:
     var allTables = app.activeDocument.stories.everyItem().tables.everyItem();
     var firstRowCells = allTables.rows[1].cells.everyItem().getElements();
         (There has to be a way to optimize that???)
2.) Call a bunch of for statements for the amount of rows I need to process (10) per table:
         for(var i = 0; i < firstRowCells.length; ++i)
               var a = parseFloat(firstRowCells[i].contents);
               if(a <= 80.00)
                     firstRowCells[i].texts[0].appliedCharacterStyle = "FAIL Red";
               } else if(a > 80.00){
                     firstRowCells[i].texts[0].appliedCharacterStyle = "PASS Green";
...all of this (about 10 for statements) results in a pretty rough crash. Anybody have a solution? Or at least an optimization tip?
Thanks,

Answer 1

The goal is to make it as automated as possible, as these 1,000 page documents will be occurring about twice a week (as far as I know).
Here is what I'm looking at now with six rows programmed for a demo of my situation (figured I'd include a dummy first row for example):
The grep style hasn't changed, except varies from line to line to meet the goal criteria, but here is the code for the six rows. Again, all I need it to do is make the same code work in the same way on all tables in the document and we're golden. This seems like the right approach, though, as it is much faster than the parseFloat() call method. (Sorry about the hard to read code...for some reason it doesn't paste well into these forums??)
var cStyles = app.activeDocument.characterStyles;
                              if((cStyles.item("FAIL Red") != null) && (cStyles.item("PASS Green") != null))
                                        for(var i = 2; i < 6; ++i)
                                                  firstRowCells[i].appliedCellStyle = "80";
                                                  firstRowCells[6].appliedCellStyle = "Trend";
                                                  firstRowCells[7].appliedCellStyle = "80";
                                        pBar.hit();
                                        for(var i = 2; i < 6; ++i)
                                                  secondRowCells[i].appliedCellStyle = "80";
                                                  secondRowCells[6].appliedCellStyle = "Trend";
                                                  secondRowCells[7].appliedCellStyle = "80";
                                        pBar.hit();
                                        for(var i = 2; i < 6; ++i)
                                                  thirdRowCells[i].appliedCellStyle = "80";
                                                  thirdRowCells[6].appliedCellStyle = "Trend";
                                                  thirdRowCells[7].appliedCellStyle = "80";
                                        pBar.hit();
                                        for(var i = 2; i < 6; ++i)
                                                  fourthRowCells[i].appliedCellStyle = "40";
                                                  fourthRowCells[6].appliedCellStyle = "Trend";
                                                  fourthRowCells[7].appliedCellStyle = "40";
                                        pBar.hit();
                                        for(var i = 2; i < 6; ++i)
                                                  fifthRowCells[i].appliedCellStyle = "50";
                                                  fifthRowCells[6].appliedCellStyle = "Trend";
                                                  fifthRowCells[7].appliedCellStyle = "50";
                                        pBar.hit();
                                        for(var i = 2; i < 6; ++i)
                                                  sixthRowCells[i].appliedCellStyle = "30";
                                                  sixthRowCells[6].appliedCellStyle = "Trend";
                                                  sixthRowCells[7].appliedCellStyle = "30";
                                        pBar.hit();
                              } else {
                                        alert("Please setup character styles for PASS Green and FAIL Red, and re-run the program.");
Thanks again, Trevor, for all the help!!

Edit: Actually...it didn't paste too too poorly after all once I clicked "Post"...hmmmm...
