I am writing a thesis and I want to change the numbering style in list of table and list of figures from "1.1 to Fig 1.1" and from "1.1 to Table 1.1" as shown below.
List of Figures
Fig. 1,1: This is figure vvvvv
Fig. 2,1: This is figure blah blah
Fig. 3,1: This is figure blah blah
List of Tables
Table 1,1: This is figure blah blah
Table 1,3: This is figure blah blah
Table 4,1: This is figure blah blah
Your question is confusing. For instance you say you want to change numbering in the LoF from "1.1" to "Fig 1.1" but later you show your expected result as "Fig. 1,1:". You don't say what class you are using but assuming it might be
report(or any other reasonable class for a thesis) then you can use the
tocloftpackage like below to change the figure numbering from "1.1" etc. to "Fig 1.1:" etc.
> texdoc tocloft) for details of what the above
Changing the figure/table numbering from "1.1" to "1,1" as in your example is a completely different question, as is your exampled desire not to have unnecessary line breaks between the LoF/LoT entries.
