           Summary: LibreOffice Writer Table Measurement Width problem
                    Error of 1mm cannot remove completely
           Product: LibreOffice
           Version: 7.1.4.2 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

Description:
Using LO 7.1.4.2 X64. Creating tables in Writer [Web View format] with columns
of exact widths and I am getting a continuing error of .01cm which no matter
how long I try to get rid of, it keeps coming back, corrupting the exact width
of the table and of some columns. If I try to correct I have to edit each
column, then the table width until I finally get the precise measurement and I
save. However on opening the document its out again.
I had measurement set to cms but recently changed to mm to try to get  the
widths more precisely. This is when I noticed that the table width can be set
to say 550mm with a From the left of 5mm. Except the width keeps reverting to
555.01 and the from the left setting changes to 4.99mm
I cannot get the 4.99mm setting to change to 5mm even if I readjust the table
width.
Thee is also an error when setting the page style with margins of 5 mm... the
settings change to 4.99mm and will not remain saved when changed to 5mm.
This has been happening for a few years but today I decided I need to bug
report it.

Steps to Reproduce:
1.Create a table - I used 300.00 mm and use Web View
2.set alignment from the left 5.00 mm
3.save the settings
4. Open Table Property settings and I get width of table  300.00 and from the
left spacing is now 4.99mm.
5. Then try using the Manual alignment.
6. table width is 300 mm left spacing field  is 4.99mm, right spacing field now
shows 330.01  [I have page style format width set to 600mm with 10.0 mm margin
left and right, Manual]
7. Now try and adjust the spacing fields to get a left field of 5.00 mm
8. at some point you an get 5.50mm in the left field but use the arrow key to
reduce it down to  5.00mm and it becomes 4.99 again and the Right field changes
to xxx.x1mm
9.Still using Manual Alignment, change the Table width to 250 mm and a left
spacing to 10.mm and try to 

1. Open a Writer document:  page style Format A4 width 297mm height 210mm. I
set to landscape with 20mm margins left/right. I changed the default text to
Calibri as I prefer it.
On the page screenshot this looks accurate. [Note: Why the A4 page  is 297mm
and not 295mm or better yet 300.00mm,  which would be mathmatically much easier
is illogical.]
2. Look at the organizer tab and you will see error no 1 – in the contains
section. The first number is 210.01mm and this is where the error begins to
appear. The fiootnote tab aslo shows a Space t text field of 1.01mm and a
spacing to footnote contents field with 1.01mm.
Change these fields to 1.00mm and applying the change does not save but reverts
back to 1.01mm when you look at the organiser again.
3. Using the Table Insert table function to insert a table 2 columns and 2
rows. Table width on my document is 257mm
4. Using table properties, change the table width to 200mm as it is easier to
evenly split columns into even spaces [I require accurate measurements for
instance in .05mm increments ie some columns are 30mm, and those may be split
into 15 mm then further split those to 7.mm etc]
5. So start with manual radial selected and table width 200mm. Now you want to
get a 10mm left spacing. Then use the up and down arrow to change the spacing
fields. Now the problems begin. Table width will change for instance to 200.01
so using the arrow you change the left field to 10.mm and the spacing right
field changes to 46.99, great, so you go click ok to save. Then open up table
properties and it’s reverted back to 200.01, but you have your correct left
field of 10mm. So you try and change the table width again with the down arrow
and save but it doesnt work. So next time adjust the Spacing right arrow field
to 47.00mm which should change the table width to 200.00mm right. Just dont
click on any field before saving though because that changes everything. So you
ok the changes and then open the Table Properties box again. This time the
table width could be 199.99 mm and a left spacing field of 10.00 mm but you
have a right field of 47.01mm which is not right. So you adjust again, this
time you change the table width to 200.00mm and put the cursor in the field to
set it before changing the right field down with the arrows to 47.00 mm because
that .01mm causes problems when creating more columns. But you cant change the
field to 47.00 and the table width has altered again to 199.99mm.
Go back to increasing the table width to 200 with the up arrow, which you can
do. Go back to the 47.01 but this time increase it to 47.50 and take a hit on
the width. Ok the change. Yes changes saved. But you really just want the 200
width table because it’s too hard to work with 199.50mm width. 

No matter what you do you cannot get a width of 200.00 mm, a left margin of
10.00 mm and 47mm on the right, even if you inset the numbers in without using
the arrows as that makes it worse.
Not to say that using arrows and adjusting the left field up/down and the table
width up/down and the right field down/up is very very antiquated and
introduces the .01mm error back into the equation.
Using the columns tab of the table properties and the arrows to adjust the
columns widths results in equally uneven distribution if you have a .01mm
anywhere.
Keep clicking the ok button and reopening and the problem continues.

Actual Results:
Cant get rid of the .01mm and it causes problems if you save the document and
open it up again later. I feel like screaming.

Expected Results:
If i have a table width 0f 200mm 0r whatever, and I select a from the left or a
left margin of 10mm or 2.5mm or any other numbers I shouldnt have to keep
respacing my columns/table/margins to remove a 0.01mm error that invariably
keeps on appearing after I open a saved document

Reproducible: Sometimes

User Profile Reset: Yes

Additional Info:
I have uninstalled and reinstalled the software. I have installed a new
motherboard/ram/hard drive and reinstalled windows operating system. Still the
same old error Just this time i have decided to bug report it.

Cant find OpenGl as per the instructions listed under Is openGl enabled. But in
Options Libre Office View Graphics output is ticked with use hardware
acceleration
