Hi Bgg_005,
Based on my test, the sheet row is different from table row (“Move but don’t size with cells” selected). When we insert a sheet row, text box will move. However, when inserting a table, the Text Box doesn’t move. As a workaround, you may directly move the Text box to a proper position. You may also firstly insert sheet rows which make text box move, and then create table.
