How to delete specific cells with app script? - google-apps-script

Question

My intention is to be able to delete for example cell F1 without deleting cell F2.
var sheet = ss.getSheetByName("Questionário DQSA");
var range = sheet.getRange("B1:U1");
range.clearContent();
Here I clear the content of these cells but I would like to know how to delete them.

Answer 1

You can use Range.deleteCells(Dimension):
var sheet = ss.getSheetByName("Questionário DQSA");
var range = sheet.getRange("F1");
range.deleteCells(SpreadsheetApp.Dimension.COLUMNS);//F2 becomes the new F1

Answer 2

If you want to roll your own:
function deleteCell(shift) {
var shift=shift || "left"; //left or up
var ss=SpreadsheetApp.getActive();
var sh=ss.getActiveSheet();
var cell=ss.getActiveCell();
if(shift=="left") {
var rg=sh.getRange(cell.getRow(),1,1,sh.getLastColumn());
var vA=rg.getValues();
var row=vA[0];
row.splice(cell.getColumn()-1,1);
rg.clearContent();
sh.getRange(cell.getRow(),1,1,row.length).setValues([row]);
}
if(shift=="up") {
var rg=sh.getRange(1,cell.getColumn(),sh.getLastRow(),1);
var vA=rg.getValues();
var row=vA.map(function(r){return r[0]});
row.splice(cell.getRow()-1,1);
var col=[];
row.forEach(function(e){
col.push([e]);
});
rg.clearContent();
sh.getRange(1,cell.getColumn(),col.length,1).setValues(col);
}
}
Of course now that I know about that new method in range it's a lot easier to write. Thanks to #TheMaster
function deleteCell(shift) {
var shift=shift || "left";
var ss=SpreadsheetApp.getActive();
var cell=ss.getActiveCell();
if(shift=="left") {
cell.deleteCells(SpreadsheetApp.Dimension.COLUMNS);
}
if(shift=="up") {
cell.deleteCells(SpreadsheetApp.Dimension.ROWS);
}
}
