我尝试了几天没有成功获取列聚合。我也在无处搜索，一无所获。我希望将第1列（具有多个相同值的字符串）分组并对第6,7,8（数字）进行求和，然后在我想选择显示第6,7或8列的选项之后。
我希望我非常清楚，解决方案可以帮助很多人。
下面我想分享一些代码。
此示例类似：http://jsfiddle.net/guilhermelight1/fcqeA/80/
我也尝试过calc：function（）...
function drawVisualization() {
var query = new google.visualization.Query('https://spreadsheets.google.com/tq?key=xxxxxx&sheet=data');
query.setQuery("select B,I,J,O,P,Q,R,S,T where O is not null Order by Q desc ");
query.send(handleQueryResponse);
}
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
return;
