Dev Express Report 学习总结（四）Dev Express 动态生成XRTable使用总结

1. XRTableCell常见属性

　 XRTableCell xrTableCell = new XRTableCell();

　 A. 字体及字体大小

    xrTableCell.Font = new System.Drawing.Font("Arial", FontSize);

　 B. 内容是否可以换行

　 xrTableCell.WordWrap = False;

    C. 文本对齐方式

　 xrTableCell.TextAlignment=DevExpress.XtraPrinting.TextAlignment.MiddleLeft;

    D. 边框是否显示及边框宽度

    xrTableCell.Borders = DevExpress.XtraPrinting.BorderSide.All;

    xrTableCell.BorderWidth = 0.5F;

    E. 宽度和高度

　 xrTableCell.WidthF = 30;

　 xrTableCell.HeightF = 30;

　 F. XRTableCell文本前景色

    xrTableCell.ForeColor=Color.Red;

    G. XRTableCell文本内容左右间隔；

　 DevExpress.XtraPrinting.PaddingInfo padRight= new DevExpress.XtraPrinting.PaddingInfo();
    padRight.Right = 4;

    XRTableCell xrTableCell = new XRTableCell();
    xrTableCell.Padding = padRight;

2. xrTable合并单元格(主要针对旧版本)

在新做的一个页面要用到xrTable合并单元格。我先在Design界面加了一个GroupHeader，随后又在GroupHeader中放了一个XRPanel，最后在XRPanel放入由xrTable嵌套的实现合并XRTableCell的功能，最后导致每一页在切换到下一页时输入很奇怪的一条线，最后查了两三天才发现这个问题。后来经过确认其实不需要加XRPanel的，直接放入嵌套的xrTable就可以了，深刻的教训，值得深思！
