How to check my data tables
1) Click on your table and make sure it’s not a picture. (If the Picture Tools Tab shows in the Ribbon, then it is a picture).
2) Verify that you do not have any merged or split cells by showing the table gridlines Table Tools Layout Tab>Table Group>View Gridlines button
3) Place your cursor on any cell in the Header Row. Open the Reveal Formatting Pane (Shift + F1). Under Table Row, ensure “Repeat as header row” is identified.
When you create a table using the directions above, MS Word automatically places the table inline. However, you can check this by right clicking (or Shift F10) on your table, selecting Table Properties>Text Wrapping and ensuring “None” is highlighted.
