Hello Hopkins,
I just wanted to tell you, your code is gorgeous! And your very talented!
Everything you create is just an absolute joy to look at. Especially the page range function.
Thanks for your understanding for what me want.

Here my changes (for your review):
try {
    //assumes document is open
    var docRef = app.documents.item(0);
    var maxPages = docRef.pages.count();
  //provide variable to hold user's response
  var userResponse = dialogWChoices ("Dialog Name", true, "Label here", maxPages);
    //enter call to function that processes all pages
    if (userResponse[0] == 0) {
        myProcess (docRef, 0, maxPages);
     } else {
         var minPageRef = userResponse[1] - 1;
         var maxPageRef = userResponse[2] - 1;
         myProcess (docRef, minPageRef, maxPageRef);
} catch (e) {
alert ("Process Done!\rWith the selected pages.");
//function to process range of pages
function myProcess (docRef, minPageRef, maxPageRef) {
    var thisPage, thisFrame, docOffset;
    //our code start from here
    var myStep = 1; 
   for (var i = minPageRef; i <= maxPageRef; i++) {
       thisPage = docRef.pages.item(i);
       var myTables = thisPage.textFrames[0].tables.everyItem().getElements();
       for (j =0; j<myTables.length; j++){
           if(myTables[j].spaceAfter  + myStep<0){myTables[j].spaceAfter = 0; continue};
           myTables[j].spaceAfter = myTables[j].spaceAfter + myStep;
          } //end our code
//function gets page range or "all" from user
function dialogWChoices (dlgName, cancelIt, dLabel, maxPages) {
    var userCancelled = false;
    var origValue = app.scriptPreferences.userInteractionLevel;
  //make sure that user interaction levels will allow a dialog
  app.scriptPreferences.userInteractionLevel = UserInteractionLevels.INTERACT_WITH_ALL;
  //create the dialog
  var dlgRef = app.dialogs.add({name:dlgName, canCel:cancelIt, label:dLabel});
  //add a column
  var dlgColumn1 = dlgRef.dialogColumns.add();
    var dlgColumn2 = dlgRef.dialogColumns.add();
    var dlgColumn3 = dlgRef.dialogColumns.add();
  //add widgets for first column
  dlgColumn1.staticTexts.add({staticLabel: "PageRange:"});
  //add widgets to second column
  var radioGroup = dlgColumn2.radiobuttonGroups.add();
    radioGroup.radiobuttonControls.add({staticLabel:"All", checkedState:true});
    radioGroup.radiobuttonControls.add({staticLabel:"Range", checkedState:true});
    //add widgets to third column; put reference into a variable
    var emptyRow = dlgColumn3.dialogRows.add();
    emptyRow.staticTexts.add ({staticLabel: ""});
    var inputRow = dlgColumn3.dialogRows.add();
    var firstField = inputRow.integerEditboxes.add({minWidth:36, minimumValue:1,maximumValue:maxPages});
    inputRow.staticTexts.add ({staticLabel: " thru "});
    var secondField = inputRow.integerEditboxes.add({minWidth:36, minimumValue:1, maximumValue:maxPages});
  //show the dialog and capture the result
  if (dlgRef.show() == true) {
        var firstVal = 0;
        var secondVal = 0;
        var selButton = radioGroup.selectedButton;
        if (selButton == 1) {
  var firstVal = firstField.editValue;
  var secondVal = secondField.editValue;
  } else {
        userCancelled = true;
       dlgRef.destroy();
       app.scriptPreferences.userInteractionLevel = origValue;
    if (userCancelled) {
       throw ("User Cancelled");
  //destroy the dialog; script doesn't get here if user cancels
  return [selButton, firstVal, secondVal];
