maybe it can not auto start new page ?

Hi! If I'm being honest, I don't fully understand what the problem is.
If you want the component to be split into parts and moved to another page, the DataBand it needs to be splitable.
startNewPage starts rendering the band from a new page.
startFromNewPage breaks the DataBand and ReportHeader, without setting this flag, the ReportHeader will be on the same page.

maybe rect calculation error？
QString(R"(<td style='padding-right: 50px; padding-bottom: 10px; white-space: pre;'>%1</td>)").arg(text)
the databand should not be on the page footer

I encountered a new (above) problem when I tried to reproduce the bug
(maybe i didn't use datasources before)

reproduce the bug when the row count is 1.

[Jacyking]

so if i don't know the column count, i should how to do ?

[fralx]

It seems that you have a misunderstanding about how LimeReport generates reports.
A report consists of individual independent elements within which you can use HTML to format the text of that specific element.

so if i don't know the column count, i should how to do ?

At the moment there is no easy way to solve that issue
