VS ReportViewer RDLC - 如何防止表格下推其他项目？

I have a narrow table on a report with 6 columns. The table has to hold 1 - 4 rows, depending on the data. I designed the report so that there is enough white space to accommodate 4 rows. I want to use the space on the right side of the table. When I place text fields there, they get pushed down by the table as it expands to show additional rows. Is there a way to lock these text fields into place?I have a narrow table on a report with 6 column
