{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("tables.docx");
//Get the first section in the document
Section sec = doc.Sections[0];
//Remove the first table in the section
sec.Tables.RemoveAt(0);
//Save the result document
doc.SaveToFile("RemoveATable.docx", FileFormat.Docx);
}
}
}
Remove All Tables in Word in C#
To delete all tables from a Word document, you need to iterate through all sections in the document, then iterate through all tables in each section and remove them through the Section.Tables.Remove() method. The following are the detailed steps.

namespace RemoveAllTable
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("tables.docx");
//Iterate through all sections in the document
foreach (Section section in doc.Sections)
{
//Iterate through all tables in each section
foreach (Table table in section.Tables)
{
//Remove the tables
section.Tables.Remove(table);
