不需要时，表格会自动调整大小。
这是我针对您的上一个问题运行的代码，使用的Excel文件包含一个表“Table1”，该表由3列和3行组成，并带有标题行，因此表的范围为A1：C4。该代码添加了另外两行，一行作为单独的单元格，另一行作为元组。随着每添加一行，表的大小都会增加，以包含添加的行。

import xlwings as xw

workbook = 'table1.xlsx'

wb = xw.Book(workbook)
ws = wb.sheets('Sheet1')

print("Original Table")
table = ws.cells.table
print("Table Range: " + str(table.range.address))

# Added data by cell
ws.range('A5').value = '444'
ws.range('B5').value = '333'
ws.range('C5').value = '222'
table2 = ws.cells.table
print("Table Range after 1 row added: " + str(table2.range.address))

### Added row
ws['A6'].value = [111, 999, 987]
table3 = ws.cells.table
print("Table Range after 2nd row added: " + str(table3.range.address))

wb.save(workbook)
wb.close()

输出

Original Table  
Table Range: $A$1:$C$4

Added rows  
Table Range after 1 row added: $A$1:$C$5  
Table Range after 2nd row added: $A$1:$C$6
