This tutorial will show you how to alternate the colors by row.
The first part will select by variables the active Spreadsheet, the sheet named Sheet1 and the range area.
The for loop will parse all rows by modulo and set a variable named range_input.
The color are changed by the setBackgrounds.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | // set alternate colors by Row function alternate_Colors_byRow() { var spread_active = SpreadsheetApp.getActiveSpreadsheet(); var sheet = spread_active.getSheetByName("Sheet1"); var range_input = spread_active.getRange("A1:B50").getValues(); for(var i=0; i<range_input.length; i++){ if(i%2==0){ for(var k=0;k<range_input[0].length;k++){ range_input[i][k]='#ffffff' } } else{ for(var k=0;k<range_input[0].length;k++){ range_input[i][k]='#0076b0' } } } sheet.getRange('A1:B50').setBackgrounds(range_input); } |
This is the output:
