Conditional formatting breaks in template with multiple tables one below other

[pledominykas]

Conditional formatting breaks when used inside template with multiple tables one after the other.

Template broken: repro-template-broken.xlsx

Template working: repro-template-working.xlsx

Code:

using ClosedXML.Report;

var data = new
{
    Directors = new[]
    {
        new { Director = "Steven Spielberg", Movie = "Jaws" },
        new { Director = "Quentin Tarantino", Movie = "Pulp Fiction" },
        new { Director = "Steven Spielberg", Movie = "E.T." },
        new { Director = "Quentin Tarantino", Movie = "" },
        new { Director = "Steven Spielberg", Movie = "Jurassic Park" },
        new { Director = "Quentin Tarantino", Movie = "" },
        new { Director = "Steven Spielberg", Movie = "Indiana Jones" },
    },
    Genres = new[]
    {
        new { Movie = "Jaws", Genre = "Thriller" },
        new { Movie = "Pulp Fiction", Genre = "" },
        new { Movie = "E.T.", Genre = "Sci-Fi" },
        new { Movie = "Kill Bill", Genre = "" },
        new { Movie = "Jurassic Park", Genre = "Sci-Fi" },
        new { Movie = "Reservoir Dogs", Genre = "Thriller" },
        new { Movie = "Indiana Jones", Genre = "" },
        new { Movie = "E.T.", Genre = "Family" },
        new { Movie = "Jaws", Genre = "Horror" },
    },
    Actors = new[]
    {
        new { Movie = "Jaws", Actor = "Roy Scheider" },
        new { Movie = "Pulp Fiction", Actor = "John Travolta" },
        new { Movie = "E.T.", Actor = "" },
        new { Movie = "E.T.", Actor = "Henry Thomas" },
        new { Movie = "Kill Bill", Actor = "" }
    },
};

void GenerateWithClosedXML()
{
    const string outputFile = "./output.xlsx";
    var template = new XLTemplate(@"./repro-template-broken.xlsx");
    // var template = new XLTemplate(@"./repro-template-working.xlsx");

    template.AddVariable(data);
    template.Generate();

    template.SaveAs(outputFile);
}

GenerateWithClosedXML();

Repro steps:

1. Run attached code
2. Observe conditional formatting is applied in wrong place

Results: Template should color the cell in red if value is empty:

However after generating the output conditional formatting breaks for the second table:

Note: if the gap between tables is more than 4 lines conditional formatting is applied correctly (as seen in repro-template-working.xlsx)
