webix.toExcel($$(“gridRpt”), {
filename: “test”,
styles: true,
spans: true,
name: “test”,
docHeader: “test”,

What’s the problem for these codes ??? Excel export documents header error

I can confirm the issue, thank you for the report! The bug will be fixed in the next patch release of Webix.

Unfortunately, so far, there is no feasible workaround for this issue, as most of the related logic is private (thus, it cannot be modified from outside).
