请问一下，dolphindb中delimiter能是tab符么？

Question

请问一下，在DolphinDB database中如下代码：

t1=table(1..6 as id,2..7 as v, 3..8 as v1, 4..9 as v2, 5..10 as v3 );
saveText(t1, "trades.txt","\t");

执行以上语句报错：
Error Message: Usage: saveText(obj, filename, [delimiter=','], [append=false]). The delimiter must be a character.

Answer 1

双引号改成单引号即可

saveText(t1, "trades.txt",'\t');
