This was happening to me on a simple table.

I had to copy the tab setting to the clip board.
Close the stack.
Open the stack.
Paste into the tab settings (column widths)
No matter how many time I changed the tab setting by hand afterwards
It would was adjust.

Kind of a paid but only needed to work for 5 mins.

Subject: Fixed width table in LC5.5?

Using LC 5.5 on MacOSX Lion 10.7.3, I am trying very minimally to follow the
example in the 5.5 Release Notes, where it says:

> vGrid fixed width table mode (5.5 DP1)
> When vGrid is in effect, if the final tabStop has 0 width the engine
treats the paragraph as a fixed
> 
> width table, the width being the position of the final tabstop.
> 
> In this mode, the width of the paragraph is considered to be the (fixed)
width and this width is used to do the following:
> 
> 	? compute the placement of the table in the line taking into account
the textAlign property
> 
> 	? compute the background rectangle to fill with the backColor
property
> 
> 	? compute the placement of the border (if any)
> 
> In this mode, rather than borders and background fill going from left
margin to right margin, they will instead go from left of the table to right
of the table.
> 
> For example, suppose you want a table-like layout with only 5 columns of
50 wide. You can use the following tabStops:
> 
> 50,50,50,50,50,0
> 
> This will result in a table of width 250 pixels.

Well, when I create a mainstack and put a table onto the first (only) card,
check that its vGrid is true and do

set the tabStops of fld "myTable" to 50,50,50,50,50,0

The property inspector for the table shows the tab stops to be at
50,100,150,200,250,250, which seems to show that I am actually setting the
tabWidths by this statement - seems weird to me. However, the real issue is
that I get a table where not all the columns are the same width (the first
one is about 2mm wider than the next two, but I suppose this may be the
effect of the border), and where the right hand edge can be infinitely
extended by dragging, making the fourth column variable rather than fixed.

I also found the IDE freezes frequently during these tests. When I force
quit, the 'do you want to Save' dialog appears briefly, but can't be
actioned, showing perhaps that the IDE was doing something; but it won't
react to mouse clicks. I find that if I reopen my stack and try to switch to
the browse tool (I thought of typing something into my table) then the
freeze occurs. I have also had a freeze after trying to set the tabWidths
and then opening an inspector for the table.

I am not trying to use the full power of the new field object, but merely to
make a grid which looks like a spreadsheet table. I liked the idea of a
table with a fixed number of columns and rows, and also one where some
columns couldn't be written to by the user. Looks like I'm barking up the
wrong tree. I have never tackled Datagrids, but this may be the moment.

Anyone else having trouble with this?

Graham

Incidentally, the property 'Cell Formatting" in a table field inspector is
not explained in the LC documentation. Does anyone know what it does?
