当前的水平渲染逻辑似乎只支持当占位符渲染为嵌套表格（Table）时的情况。如果占位符被替换为纯文本或其他类型的元素，newTr.Descendants<Table>().FirstOrDefault() 将返回 null，导致 elementList 为空，水平渲染逻辑不会添加任何内容。这使得该功能在处理非表格内容时会失效，是一个比较严重的缺陷。需要将此逻辑通用化，以捕获被渲染单元格内的所有类型内容。


if (index > 0 && (index + 1) % num == 0 && elementList.Count > 0)
{
var templateTr = tr.CloneNode(true);
for (var i = 0; i < elementList.Count; i++)
{
var tCell = templateTr.Elements<TableCell>().ToList()[i];

tCell.RemoveAllChildren();
tCell.Append(elementList[i]);
}
newTr = templateTr;
elementList = new List<OpenXmlElement>();

table.Append(newTr);
}
}
else
{
// If it is a nested table, temporarily append it to the end according to the original plan.
table.Append(newTr);
//Fix #47 The table should be inserted at the template tag position instead of the last row
if (table.Contains(tr))
{
table.InsertBefore(newTr, tr);
}
else
{
// If it is a nested table, temporarily append it to the end according to the original plan.
table.Append(newTr);
}
}
index++;
}

tr.Remove();

在水平渲染模式下（isHorizontal为true），如果数据列表中的项目总数不是表格列数的整数倍，循环结束后elementList中剩余的项目将会被丢弃，不会被渲染到文档中，这会导致数据丢失。您需要在循环之后添加逻辑来处理这些剩余的项目，为它们生成最后一行。

                        }

                        if (isHorizontal && elementList.Any())
                        {
                            var templateTr = tr.CloneNode(true);
                            var cells = templateTr.Elements<TableCell>().ToList();
                            for (int i = 0; i < cells.Count; i++)
                            {
                                var tCell = cells[i];
                                tCell.RemoveAllChildren();
                                if (i < elementList.Count)
                                {
                                    tCell.Append(elementList[i]);
                                }
                            }
                            table.Append(templateTr);
                        }
