Examples

Shows how to remove the first and last rows of all tables in a document.

let doc = new aw.Document(base.myDir + "Tables.docx");

let tables = doc.firstSection.body.tables.toArray();

expect(tables[0].rows.count).toEqual(5);
expect(tables[1].rows.count).toEqual(4);

for (var table of tables)
{
  table.firstRow?.remove();
  table.lastRow?.remove();
}

expect(tables[0].rows.count).toEqual(3);
expect(tables[1].rows.count).toEqual(2);

Shows how to find out if a tables are nested.

test('CalculateDepthOfNestedTables', () => {
  let doc = new aw.Document(base.myDir + "Nested tables.docx");
  let tableNodes = doc.getChildNodes(aw.NodeType.Table, true);
  expect(tableNodes.count).toEqual(5);

  for (let i = 0; i < tableNodes.count; i++)
  {
    let table = tableNodes.at(i).asTable();

    // Find out if any cells in the table have other tables as children.
    let count = getChildTableCount(table);
    console.log("Table #{0} has {1} tables directly within its cells", i, count);

    // Find out if the table is nested inside another table, and, if so, at what depth.
    let tableDepth = getNestedDepthOfTable(table);

    if (tableDepth > 0)
      console.log("Table #{0} is nested inside another table at depth of {1}", i,
        tableDepth);
    else
      console.log("Table #{0} is a non nested table (is not a child of another table)", i);
  }
});

function getNestedDepthOfTable(table) {
  let depth = 0;
  let parent = table.getAncestor(aw.NodeType.Table);

  while (parent != null)
  {
    depth++;
    parent = parent.getAncestor(aw.NodeType.Table);
  }

  return depth;
}
