CS3 [JS] Speed Issues with Table Formating

Hi there

Please find below an excerpt from my table formatting script. Script as such runs perfectly and does its job well. But it's quite slow thanks to the "formatTable" function (at least that's what Extend Script profiler says).

What I want it to do is to set the same border for each cell. In its current state it takes it three to five minutes to crunch through 300 rows.
So I naturally started to wonder whether I'm really doing it the most clever way.

Thanks for Help

function formatTable(){
//~ myTable.cells.everyItem().bottomEdgeStrokeType="Solid";
//~ myTable.cells.everyItem().topEdgeStrokeType="Solid";
//~ myTable.cells.everyItem().leftEdgeStrokeType="Solid";
//~ myTable.cells.everyItem().rightEdgeStrokeType="Solid";
//~ myTable.cells.everyItem().bottomEdgeStrokeWeight=".25pt";
//~ myTable.cells.everyItem().topEdgeStrokeWeight=".25pt";
//~ rightEdgeStrokeWeight=0;
//~ myTable.cells.everyItem().leftEdgeStrokeWeight=0;

for (i=myTable.rows.length;i>0;i--){
focus = myTable.rows[i-1].cells.everyItem();
with (focus){
bottomEdgeStrokeType="Solid"; topEdgeStrokeType="Solid"; leftEdgeStrokeType="Solid"; rightEdgeStrokeType="Solid";
bottomEdgeStrokeWeight=".25pt"; topEdgeStrokeWeight=".25pt"; rightEdgeStrokeWeight=0; leftEdgeStrokeWeight=0;
}
$.writeln("Formating Table: " + i + "/" + myTable.rows.length);
}
