Issue Details

I am using a table control in LabWindows™/CVI™. I cannot enable the table column headings to show in my .uir file (shown below).

They show up fine in one of the LabWindows/CVI example projects. Why won't the column headings show up and what can I do to display them?


There are two things that you will need to check if you see this behavior:
  1. Make sure that you have Columns and Rows in the table. If a table does not have Rows and Columns, you won't see anything in the Table Control on your User Interface (.uir). You can right click on the Table Control, and go to Edit Control (shown below) to add Rows and Columns.

  1. If you do have Rows and Columns in your table, please ensure that the column headers haven't been hidden via clicking and dragging the bottom edge of the column header. You can show the column headers by finding the bottom edge, and clicking and dragging to expand it.
