Google-sheets – Is it possible to hide row numbers in a Google Sheets

The code below will get all unique names from the sheet names 1 through 14 sheets and perform a summation.

Code

function getTotals() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var uniqueNames = [], allData = [], output = [];

  // itterate through the sheets and retrieve info  
  for(var i=1; i<14; i++) {
    this.sh = ss.getSheetByName(i); 
    this.lRow = this.sh.getMaxRows();
    this.names = this.sh.getDataRange().getValues();
    var a = this.names;

    // gather unique names and data
    for(var j=4, jLen=a.length; j<jLen; j++) {
      if(a[j][1].length > 0) {
        if(uniqueNames.indexOf(a[j][1]) == -1) {
          uniqueNames.push(a[j][1]);
        }          
        allData.push([a[j][1],a[j][2],a[j][3]]);
      }
    }    
  }

  // sort all the data for efficient processing
  var sData = allData.sort(), sNames = uniqueNames.sort();

  // itterate throught the names and perform sum
  for(var l=0, lLen=sNames.length; l<lLen; l++) {
    var sum1=0, sum2=0;
    for(var m=0, mLen=sData.length; m<mLen; m++) {
      if(sNames[l] == sData[m][0]) {
        sum1 += sData[m][1], sum2 += sData[m][2];
      }      
    }
    output.push([sNames[l], sum1, sum2]);
  }
  return output;
}

Remark

Make a copy of the spreadsheet and goto Tools>Script editor

Example

I've created a copy of your file and added the solution to it: Sum Through Sheets

To sort a query you simply have to wrap it in SORT.

=SORT(
    QUERY(
        {SheetOne!C3:F;SheetTwo!C3:F;SheetThree!F4:G;SheetFour!F4:G}
    )
    , 1, TRUE)

For example, the above formula takes the data from the sheets inside the query, and then sorts by ascending order from column 1.

This also works well to solve the problem of row splitting, where some rows get split up if you use different queries to pull from rows you intend to keep uniform.
