rust_xlsxwriter 中的条件格式顺序问题

Question

我对条件格式的顺序有疑问 我正在尝试制作一个具有 20 个条件格式的新 Excel 工作表 它们在某些单元格中重叠，但是当我打开工作表时，顺序颠倒了，我尝试颠倒代码中的范围

for i in (0..19).rev() {

，但它不起作用，我也尝试使用硬代码而不是循环，并按顺序播放代码和它总是给我相同的结果，我做错了什么吗？

    let color_array: [(u32, u32); 20] = [
        (0x0000ff, 0xffff00),
        (0x80ff80, 0x000000),
        (0xffff00, 0x3a00ff),
        (0x0000ff, 0xffffff),
        (0xff0000, 0xffffff),
        (0x80ffff, 0x000000),
        (0xff80ff, 0x000000),
        (0xffff80, 0x000000),
        (0x000000, 0xffffff),
        (0xc0c0c0, 0xffffff),
        (0x008000, 0xffffff),
        (0x0000a0, 0xffffff),
        (0x804000, 0xffffff),
        (0x800080, 0xffffff),
        (0xff8040, 0xffffff),
        (0x8080c0, 0xffffff),
        (0x808040, 0xffffff),
        (0x808080, 0xffffff),
        (0x408080, 0xffffff),
        (0x8080c0, 0xffffff),
    ];

//

//
    for i in 0..19 {
        let form = Format::new()
            .set_background_color(Color::RGB(color_array[i].0))
            .set_font_color(Color::RGB(color_array[i].1))
            .set_border_color(Color::RGB(BORDER_COLOR))
            .set_border_top(FormatBorder::Thin)
            .set_border_bottom(FormatBorder::Thin)
            .set_bold()
            .set_align(FormatAlign::Center);

        let rule = format!("$W4>={}", i + 1);
        let conditional = ConditionalFormatFormula::new()
            .set_rule(rule.as_str())
            .set_format(form);
        worksheet.add_conditional_format(3, i as u16, MAX_ROWS, 22, &conditional)?;
    }

顺序错误 想要的结果

我尝试制作一个包含 20 个条件格式的 Excel 工作表和订单，但我无法收到此订单

Answer 1

深入研究问题后，我试图找出根本原因，看看是什么因素影响了这个问题

我发现它与

add_conditional_format()

方法和规则被排序为行/列顺序而不是插入顺序仅与嵌套范围

我提出了一个 GitHub 问题，该问题已在版本“0.79.1”中修复 该问题出现在版本“0.79.0”中

这是更改日志：

• 修复了未保留条件格式的优先顺序并且规则被排序为行/列顺序而不是插入顺序的问题。此问题仅在嵌套条件格式中才会出现，不会影响大多数用户。
