单词互操作单元格自定义文本选择

就我而言，我需要在表格的某个单元格中使用自定义文本。所有单元格必须具有垂直和水平对齐方式。倒数第二行必须是斜体，此单元格中的最后一行必须是粗体和绿色。它必须是这样的：

Some regular text: some text
Some other text: some text
Italic text:
BOLD GREEN TEXT

所有这些都必须在一个牢房里。我尝试写第一行，然后更改单元格。范围参数并添加下一行，但不幸的是，范围方法更改了所有单元格样式。我的代码：（t1 - 我的表）

 Word.Table t1 = worddocument.Tables.Add(wordrange, 8, 3, ref defaultTableBehavior, ref autoFitBehavior);
                    t1.Cell(1, 2).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter;
                    t1.Cell(1, 2).Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;
                    t1.Cell(1, 2).Range.Text = "Tester: " + ini.IniReadValue("Main", "Name") + "'nDate: " + DateTime.Today.ToShortDateString() + "'n";
                    t1.Cell(1, 2).Range.Italic = 1;
                    t1.Cell(1, 2).Range.Text = "Italic text"; 

我也试图创建一些段落，但没有任何好事发生。

private Word.Paragraphs wordparagraphs;
private Word.Paragraph wordparagraph;
object oMissing = System.Reflection.Missing.Value;
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
wordparagraphs = t1.Cell(1, 2).Range.Paragraphs;
wordparagraph = (Word.Paragraph)wordparagraphs[1];
t1.Cell(1, 2).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter;
t1.Cell(1, 2).Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;
wordparagraph.Range.Text = "Tester: " + ini.IniReadValue("Main", "Name") + "'nDate: " + DateTime.Today.ToShortDateString() + "'nComponent: " + tabControl1.SelectedTab.Name + "'n";
wordparagraph = (Word.Paragraph)wordparagraphs[2];
wordparagraph.Range.Italic = 1;
wordparagraph.Range.Text = "Italic text"; 

结果，"斜体文本"与第一段的第二行重叠。那么如何更改一个单元格中的一些文本呢？

t1.Cell(1,2).Range.ParagraphFormat.LineSpacing = 12; 
t1.Cell(1, 2).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter;
t1.Cell(1, 2).Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;
object oMissing = System.Reflection.Missing.Value;
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
wordparagraphs = t1.Cell(1, 2).Range.Paragraphs;
    wordparagraphs[1].Range.Text = "Tester: " + ini.IniReadValue("Main", "Name");
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
    wordparagraphs[2].Range.Text = "Date: " + DateTime.Today.ToShortDateString();
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
    wordparagraphs[3].Range.Text = "Component: " + tabControl1.SelectedTab.Text;
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
    //freespace?
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
wordparagraphs[5].Range.Italic = 1;
wordparagraphs[5].Range.Text = "Task status:";
t1.Cell(1, 2).Range.Paragraphs.Add(ref oMissing);
wordparagraphs[6].Range.Bold = 1;
wordparagraphs[6].Range.Italic = 0;
if (impStatus.SelectedIndex == 0)
    wordparagraphs[6].Range.Font.ColorIndex = Word.WdColorIndex.wdGreen;
                       else 
    wordparagraphs[6].Range.Font.ColorIndex = Word.WdColorIndex.wdRed;
    wordparagraphs[6].Range.Font.Size = 18;
    wordparagraphs[6].Range.Text = impStatus.Text.ToUpper() ;
