Exception: The number of columns in the data does not match the number of columns in the range despite the range being created from data

问题

I'm trying to figure out what I'm missing here in this Google script. I keep getting the error

Exception: The number of columns in the data does not match the number of columns in the range. The data has 0 but the range has 15.

but it doesn't make sense to me.

Here's the bit of code in question:

var range = ReleaseSchedule.getRange(1,1,output_data_sheet.length,output_data_sheet[0].length);
range.setValues(output_data_sheet);

ReleaseSchedule is a new sheet in the active spreadsheet output_data_sheet is a 2 dimensional array. I have similar code working earlier in the script, but for some reason this one is throwing that exception and I can't figure out why. Any help or thoughts would be greatly appreciated.

回答1:

I thought that the reason of this error of Exception: The number of columns in the data does not match the number of columns in the range. The data has 0 but the range has 15. might be as follows.

• output_data_sheet is 2 dimensional array.
• The array length of the 1st index of output_data_sheet is 15
• The empty array (the array length is 0) is included in the index except for 1st index.

When above output_data_sheet is used for setValues(), such error might occur. In order to remove this issue, how about the following modifications? Here, I would like to propose 2 patterns.

Pattern 1:

In this pattern, the empty elements are removed from output_data_sheet.

From:

var range = ReleaseSchedule.getRange(1,1,output_data_sheet.length,output_data_sheet[0].length);
range.setValues(output_data_sheet);

To:

output_data_sheet = output_data_sheet.filter(String);  // <--- Added
var range = ReleaseSchedule.getRange(1,1,output_data_sheet.length,output_data_sheet[0].length);
range.setValues(output_data_sheet);

Pattern 2:

In this pattern, the empty elements and the element smaller than the length of 15 add the elements for keeping the length of 15 for each index in output_data_sheet.

From:

var range = ReleaseSchedule.getRange(1,1,output_data_sheet.length,output_data_sheet[0].length);
range.setValues(output_data_sheet);

To:

output_data_sheet = output_data_sheet.map(r => r.length == 15 ? r : r.concat(Array(15 - r.length).fill("")));  // <--- Added
var range = ReleaseSchedule.getRange(1,1,output_data_sheet.length,output_data_sheet[0].length);
range.setValues(output_data_sheet);
