.setColumnWidths() google script

The .setColumnWidths() method in Google Apps Script allows you to set the width of one or more columns in a Google Sheets spreadsheet. Here is an explanation of each step involved:

First, you need to access the sheet where you want to set the column widths. You can do this by using the getActiveSheet() method, which returns the currently active sheet in the spreadsheet.
Next, you'll need to specify the range of columns for which you want to set the widths. You can do this by using the getRange() method, which takes the starting and ending column indexes as parameters. For example, if you want to set the widths for columns A, B, and C, you can use getRange(1, 1, -1, 3), where the first parameter represents the starting row index, the second parameter represents the starting column index, the third parameter represents the number of rows to include (-1 means all rows), and the fourth parameter represents the number of columns to include (in this case, 3 columns).
Once you have specified the range, you can use the setColumnWidths() method on the range object obtained from the getRange() method. This method takes an array of numbers as a parameter, where each number represents the width in pixels for each column in the range. The index of each number in the array corresponds to the index of the column in the range. For example, if you want to set the widths of columns A, B, and C to 100, 200, and 150 pixels respectively, you can use setColumnWidths([100, 200, 150]).
Finally, you can use the toast() method to display a brief message to the user indicating that the column widths have been set successfully. For example, you can use toast("Column widths set!").

That's it! These are the steps involved in using the .setColumnWidths() method in Google Apps Script to set the column widths in a Google Sheets spreadsheet.
