How to delete Excel table rows and columns in C#, VB.NET?

private void DeleteTableRow(IListObject table, int rowNumber)
{

    if (firstTableRow + rowNumber < tableRange.LastRow)
    {
        for (int i = firstTableRow + rowNumber + 1; i <= worksheet.Range.LastRow; i++)
        {
            worksheet.Range[i, firstTableColumn, i, lastTableColumn].MoveTo(worksheet.Range[i - 1, firstTableColumn, i - 1, lastTableColumn]);
        }
    }
    table.Location = table.Location[firstTableRow, firstTableColumn, lastTableRow - 1, lastTableColumn];
 
    for (int i = 0; i < worksheet.ListObjects.Count; i++)
    {

        {
            tableSample.Location = table.Location[firstrow - 1, firstcolumn, tableSample.Location.LastRow - 1, tableSample.Location.LastColumn];
        }
    }
}
