Spire.Doc 13.9.10 现已发布。该版本公开了几个用于精细化文档样式控制的核心接口。此外还支持移除文档样式和添加预置表格样式等。详情如下。

新功能:

• 公开 ICharacterStyle、IListStyle和 ITableStyle 等核心接口，支持更精细的文档样式控制。
• Style接口移除了CharacterFormat属性，此属性分别在TableStyle，ParagraphStyle和CharacterStyle接口中进行实现。

IStyle style = document.Styles.FindByName("Normal");
if (style != null && style is ICharacterStyle)
{
    ICharacterStyle cStyle = style as ICharacterStyle;
    cStyle.CharacterFormat.FontName = "cambria";
    cStyle.CharacterFormat.FontSize = 14;
    cStyle.CharacterFormat.Bold = true;
    cStyle.CharacterFormat.TextColor = Color.FromArgb(42, 123, 136);
}

• Style接口提供RemoveSelf()的方法，支持移除样式。

string pStyleName = "testStyle";
Document document = new Document();
ParagraphStyle pStyle = (ParagraphStyle)document.Styles.Add(StyleType.ParagraphStyle, pStyleName);
pStyle.CharacterFormat.FontName = "Calibri";
pStyle.CharacterFormat.FontSize = 16;
pStyle.CharacterFormat.Bold = true;
pStyle.CharacterFormat.TextColor = Color.DarkRed;
Section section = document.AddSection();
Paragraph para = section.AddParagraph();
para.ApplyStyle(pStyle);
para.AppendText("Hello world!");
Style firstParaStyle = document.FirstSection.Body.FirstParagraph.Format.Style;
document.SaveToFile(outputDocxFile1, FileFormat.Docx);
document.Styles[pStyleName].RemoveSelf();
document.SaveToFile(outputDocxFile2, FileFormat.Docx);

• TableStyle 实现 ITableStyle 接口。同时新增 TableConditionalStyle、TableConditionalStyleCollection 和 TableConditionalStyleType 类型，支持对表格的奇偶行、奇偶列等条件格式进行精细化控制。

Document doc = new Document();
Section section = doc.AddSection();
Table table = section.AddTable();
table.ResetCells(15, 4);
for (int i = 0; i < 15; i++)
{
    TableRow row = table.Rows[i];
    for (int j = 0; j < 4; j++)
    {
        TableCell cell = row.Cells[j];
        cell.AddParagraph().AppendText(string.Format("{0} column.", (j % 2 == 0 ? "Even" : "Odd")));
        cell.AddParagraph().AppendText(string.Format("Row banding {0}", (i % 3 == 0 ? "start" : "continuation")));
    }
}

TableStyle tableStyle = (TableStyle)doc.Styles.Add(StyleType.TableStyle, "TestTableStyle1");
tableStyle.Borders.Color = Color.Black;
tableStyle.Borders.BorderType = BorderStyle.Double;

tableStyle.RowStripe = 3;
tableStyle.ConditionalStyles[TableConditionalStyleType.OddRowStripe].Shading.BackgroundPatternColor = Color.LightBlue;
tableStyle.ConditionalStyles[TableConditionalStyleType.EvenRowStripe].Shading.BackgroundPatternColor = Color.LightCyan;

tableStyle.ColumnStripe = 1;
tableStyle.ConditionalStyles[TableConditionalStyleType.EvenColumnStripe].Shading.BackgroundPatternColor = Color.LightPink;

table.ApplyStyle(tableStyle);

table.Format.StyleOptions = table.Format.StyleOptions | TableStyleOptions.ColumnStripe;

doc.SaveToFile(outputDocxFile1, FileFormat.Docx); 

• Table.TableStyleName 属性已标记为过时，建议使用 table.Format.StyleName替换。增加Table.Format.Style 和 Table.ApplyStyle(ITableStyle) 应用表格样式。
• TableFormat类提供了Style，StyleOptions，StyleName 属性以及 TableStyleOptions 枚举。

Document doc = new Document();
Section section = doc.AddSection();

TableStyle tableStyle = (TableStyle)doc.Styles.Add(StyleType.TableStyle, "TestTableStyle1");
tableStyle.HorizontalAlignment = RowAlignment.Center;
tableStyle.Borders.Color = Color.Blue;
tableStyle.Borders.BorderType = BorderStyle.Single;

Table table = section.AddTable();
table.ResetCells(1, 1);
table.Rows[0].Cells[0].AddParagraph().AppendText("Aligned to the center of the page");
table.PreferredWidth = PreferredWidth.FromPoints(300);

table.ApplyStyle(tableStyle);

section.AddParagraph().AppendText(" ");

tableStyle = (TableStyle)doc.Styles.Add(StyleType.TableStyle, "TestTableStyle2");
tableStyle.LeftIndent = 55;
tableStyle.Borders.Color = Color.Green;
tableStyle.Borders.BorderType = BorderStyle.Single;

table = section.AddTable();
table.ResetCells(1, 1);
table.Rows[0].Cells[0].AddParagraph().AppendText("Aligned according to left indent");
table.PreferredWidth = PreferredWidth.FromPoints(300);

table.Format.Style = tableStyle;

doc.SaveToFile(outputDocxFile1, FileFormat.Docx);

• Document类新增AddStyle(DefaultTableStyle builtinStyle) 方法，支持添加预置表格样式。

Document doc = new Document();
Section section = doc.AddSection();
Table table = section.AddTable();
table.ResetCells(15, 4);
for (int i = 0; i < 15; i++)
{
    TableRow row = table.Rows[i];
    for (int j = 0; j < 4; j++)
    {
        TableCell cell = row.Cells[j];
        cell.AddParagraph().AppendText(string.Format("{0} column.", (j % 2 == 0 ? "Even" : "Odd")));
        cell.AddParagraph().AppendText(string.Format("Row banding {0}", (i % 2 == 0 ? "Even" : "Odd")));
    }
}

TableStyle tableStyle = doc.AddStyle(DefaultTableStyle.LightListAccent3);
table.ApplyStyle(tableStyle);
doc.SaveToFile(outputDocxFile1, FileFormat.Docx);
