Chapter4:SpreadsheetsinCalc
AddressingCells
Cellscanbeaddresseddirectlybymeansoftheircoordinatesintherow­and­columnmatrix.
Useabsoluteorrelativereferencing,orgivecellrangestheirownnames.
AddressesandReferences,AbsoluteandRelative
RelativeAddressing
ThecellincolumnA,row1isaddressedasA1.Addressarangeofadjacentcellsbyfirst
enteringthecoordinatesoftheupperleftcellofthearea,thenacolonfollowedbythe
coordinatesofthelowerrightcell.Forexample,thesquareformedbythefirstfourcellsin
theupperleftcornerisaddressedasA1:B2.Byaddressinganareainthisway,oneis
makingarelativereferencetoA1:B2.Relativeheremeansthatthereferencetothisareawill
beadjustedautomaticallywhentheformulaearecopied.
AbsoluteAddressing
Absolutereferencesaretheoppositeofrelativeaddressing.Adollarsignisplacedbefore
eachletterandnumberinanabsolutereference,e.g.,$A$1:$B$2.
Calccanconvertthecurrentreference,inwhichthecursorispositionedintheinputline,
fromrelativetoabsoluteandviceversabypressingShift+F4.Whenstartingwitha
relativeaddresssuchasA1,thefirsttimethiskeycombinationispressed,bothrowand
columnaresettoabsolutereferences($A$1).Thesecondtime,onlytherow(A$1),andthe
thirdtime,onlythecolumn($A1).Pressingthekeycombinationoncemore,bothcolumn
androwreferencesareswitchedbacktorelative(A1)
Calcshowsthereferencestoaformula.If,forexampletheformula
=SUM(A1:C5;D15:D 24)isclickedinacell,thetworeferencedareasinthesheetwillbe
highlightedincolour.Forexample,theformulacomponentA1:C5maybeinblueandthe
cellrangeinquestionborderedinthesameshadeofblue.Thenextformulacomponent
D15:D24canbemarkedinredinthesameway.
WhentoUseRelativeandAbsoluteReferences
Firstexaminewhathappenswithoutarelativereference.AssumeacalculationincellE1that
sumsthecellsinrangeA1:B2.TheformulatoenterintoE1wouldbe:=SUM(A1:B2).If,
later,anewcolumnmustbeinfrontofcolumnA,theelementstobeaddedwouldthenbein
B1:C2andtheformulawouldbeinF1,notinE1.Afterinsertingthenewcolumn,all
formulaewouldthereforehavetobecheckedandcorrectedinthecurrentsheet,andpossibly
inothersheets.
Fortunately,Calcdoesthisworkautomatically.AfterinsertinganewcolumnA,theformula
=SUM(A1:B2)isupdatedto=SUM(B1:C2).Rownumbersarealsoautomaticallyadjusted
whenanewrow1isinserted.AbsoluteandrelativereferencesarealwaysadjustedinCalc
wheneverthereferencedareaismoved.Butbecarefulwhencopyingaformulasinceinthat
caseonlytherelativereferenceswillbeadjustedbutnotanyabsolutereferences.

Chapter4:SpreadsheetsinCalc
Absolutereferencesareusedwhenacalculationreferstoonespecificcellinthesheet.For
example,ifaformulathatreferstoexactlythiscelliscopiedrelativelytoacellbelowthe
originalcell,thereferencewillalsobemoveddownifthecellcoordinatesarenotdefinedas
absolute.Asidefromwhennewrowsandcolumnsareinserted,referencescanalsochange
whenanexistingformulareferringtoparticularcellsiscopiedtoanotherareaofthesheet.
Assume,forexample,theformula=SUM(A1:A9)isenteredinrow10butthecalculated
summustbeintheadjacentcolumntotheright.Inthiscase,simplycopythisformulatothe
celltotheright.ThecopyoftheformulaincolumnBwillbeautomaticallyadjustedto
=SUM(B1:B9).
Therearemanymethodstocopyaformula,oneofwhichis:
1. Selectthecellcontainingtheformula.
2. ChooseEdit>Copy,orpressCtrl+Ctocopyit.
3. Selectthecellintowhichtheformulaistobecopied.
4. ChooseEdit>Paste,orpressCtrl+V.Theformulawillbepositionedinthenewcell,
andallnon­absolutereferenceswillbeupdated.
Copyingaformulaintomultiplecellscanbequickandeasy.Onewaytocopyintoadjacent
cellareasisasfollows:
1. Selectthecellcontainingtheformula.
2. Positionthemouseonthebottomrightofthehighlightedborderofthecell,andcontinue
holdingdownthemousebuttonuntilthepointerchangestoacross­hairsymbol.
3. Withthemousebuttonpressed,dragitdownortotherightoverallthecellsintowhich
theformulawillbecopied.
4. Uponreleasingthemousebutton,theformulawillbecopiedintothecellsand
automaticallyadjusted.
Wherevaluesandtextsmustnotbeautomaticallyadjusted,thenholddowntheCtrlkey
whendragging.formulae,however,arealwaysadjustedaccordinglywhendragging.
Nowlookatwhathappenedwhenrowsandcolumnsareadded.Assumeacalculationincell
E1thatsumsthecellsinrangeA1:B2.TheformulatoenterintoE1wouldbe:
=SUM(A1:B2).If,later,anewcolumnmustbeinfrontofcolumnA,theelementstobe
addedwouldthenbeinB1:C2andtheformulawouldbeinF1,notinE1.Afterinserting
thenewcolumn,allformulaewouldthereforehavetobecheckedandcorrectedinthecurrent

Fortunately,Calcdoesthisworkautomatically.AfterinsertinganewcolumnA,theformula
=SUM(A1:B2)isupdatedto=SUM(B1:C2).Rownumbersarealsoautomaticallyadjusted

AddressingbyName
Aneatwayofmakingthereferencestocellsandcellrangesinformulaelegibleistogivethe
rangesnames.Forexample,nametherangeA1:B2asStartthenintheformulasimplyenter
=SUM(Start).FollowingtheinsertionordeletionofrowsandcolumnsOpenOffice.org
alsocorrectlyassignstherangesidentifiedbyname.Remember,rangenamescannotcontain
anyspaces.
Forexample,itismucheasiertoreadaformulaforsalestaxifwrittenas=Amount*
Tax_rateinsteadof=A5*B2.Inthiscase,cellA5wouldbenamedasAmountand
cellB2asTax_rate.
Inordertospecifyrangenames,followsthesesteps:
1. Firsthighlighttheareatobenamed.
2. SelectInsert>Names>Define,orusetheCtrl+F3keycombination.
3. Enterthenameforthefirstarea.
4. ClickAdd.
Othercellrangescanalsobenamedinthisdialoguebyenteringthedesirednameinthe
fieldandthenselectingtherespectivecells.UsetheDefineNamesdialoguetodefine
namesforformulaeorpartsofformulaeneededmoreoften.
5. ClosethedialoguewithOK.
