1. Create a table

        /// <summary>
        ///  Create a table 
        /// </summary>
        /// <param name="wordDoc"></param>
        /// <param name="rowCount"> Row number </param>
        /// <param name="cellCount"> Number of columns </param>
        /// <param name="ln"> Newline creation </param>
        /// <param name="alignment"> Paragraph alignment </param>
        public void CreateTable(Document wordDoc, int rowCount, int cellCount, bool ln, ParagraphAlignment alignment = ParagraphAlignment.Left)
        {
            DocumentBuilder builder = new DocumentBuilder(wordDoc);
            builder.MoveToDocumentEnd();
            if (ln) builder.Writeln();
            ParagraphFormat paragraph = builder.ParagraphFormat;
            paragraph.Alignment = alignment;
            builder.StartTable();
            for (int i = 0; i < rowCount; i++)
            {
                for (int j = 0; j < cellCount; j++)
                {
                    builder.InsertCell();
                }
                builder.EndRow();
            }
            builder.EndTable();
            paragraph.Alignment = ParagraphAlignment.Left;
        }

2. Add data to the table

         /// <summary>
        ///  Add data to the table 
        /// </summary>
        /// <param name="dt"></param>
        public void WriteTable(DataTable dt)
        {
            wordDoc.MailMerge.ExecuteWithRegions(dt);
        }

Example ：

 

Private void AddValueToTable()
{
    DataTable dt = new DataTable(“StudentInfo”);
    dt.Columns.Add(“Name”);
    dt.Columns.Add(“Age”);
    dt.Columns.Add(“Sex”);
    dt.Rows.Add(new object[]{ “ Zhang San ”,”18”,” male ” });
    WriteTable(dt);
}

3. Get a table

         /// <summary>
        ///  Get form 
        /// </summary>
        /// <param name="tableIndex"></param>
        /// <returns></returns>
        public Table GetTable(int tableIndex)
        {
            Table table = (Table)wordDoc.GetChild(NodeType.Table, tableIndex, true);
            return table;
        }

4. Add a line to the table

        /// <summary>
        ///  Add a row to the table 
        /// </summary>
        /// <param name="tableIndex"> The first few forms </param>
        public void AddRowItem(int tableIndex)
        {
            Table table = (Table)wordDoc.GetChild(NodeType.Table, tableIndex, true);
            Row row = (Row)table.LastRow.Clone(true);
            table.AppendChild(row);
        }

5. Delete table rows

        /// <summary>
        ///  Delete the last row of the table 
        /// </summary>
        /// <param name="tableIndex"></param>
        public void RemoveLastRow(int tableIndex)
        {
            Table table = (Table)wordDoc.GetChild(NodeType.Table, tableIndex, true);
            Row row = (Row)table.LastRow;
            table.RemoveChild(row);
        }
        /// <summary>
        ///  Delete the first row of the table 
        /// </summary>
        /// <param name="tableIndex"></param>
        public void RemoveFirstRow(int tableIndex)
        {
            Table table = (Table)wordDoc.GetChild(NodeType.Table, tableIndex, true);
            Row row = (Row)table.LastRow;
            table.RemoveChild(row);
        }
        /// <summary>
        ///  Delete a row in the table 
        /// </summary>
        /// <param name="tableIndex"></param>
        /// <param name="rowIndex"></param>
        public void RemoveRowItem(int tableIndex, int rowIndex)
        {
            Table table = (Table)wordDoc.GetChild(NodeType.Table, tableIndex, true);
            Row row = (Row)table.Rows[rowIndex];
            if(row != null)
                table.RemoveChild(row);
        }

6. Delete a column of the table

        /// <summary>
        ///  Delete a column of the table 
        /// </summary>
        /// <param name="tableIndex"></param>
        /// <param name="cellIndex"></param>
        public void RemoveCellItem(int tableIndex, int cellIndex)
        {
            Table table = (Table)wordDoc.GetChild(NodeType.Table, tableIndex, true);
            for (int i = 0; i < table.Rows.Count; i++)
            {
                Cell cell = table.Rows[i].Cells[cellIndex];
                if (cell != null)
                    table.Rows[i].RemoveChild(cell);
            }
        }

7. Assign values to cells

 /// <summary>
        ///  Set a cell value in the table 
        /// </summary>
        /// <param name="tableIndex"> form </param>
        /// <param name="row"> Lines </param>
