I found my issue. I used in template "data"

"template": { "content": "<html><head><style>" +cssContent //your css text +"</style></head><body>" +document.getElementById('yourTableID').outerHTML +"</body></html>", "shortid":"shortid", //from API info in jsreport studio "options": { "reports": { "save": true } } }

for my html code, but for sending code of table I must using "content".
Maybe it will be usable for someone.
