This function displays a window that shows which columns are visible and which are not, so if you are not sure whether any columns have been hidden, you can use Show Column to find out.
If you have used View, Hide Column to hide some columns in a window, you can make them visible again with this function.
Click View, Show Column and the Show Column window appears.
The Show Column window contains the field names of all the columns in the active window.
If there is no check mark next to a field name, that column is hidden.
To make a column visible on the screen, click to the left of the field name to place a check mark.
To leave the column hidden, leave it without a check mark.
When this function is be used to hide FlowFields on tabular forms, the FlowField is no longer calculated and this can improve performance slightly. However you might have some code on the form that uses the information in this FlowField and this will not work properly if the FlowField in question is invisible and therefore not calculated.
