Here I would like to show the word \textbf{Remark} as \textbf{\textit{Remark}} but do not know what modification should I make in preamble. Can any one help ?

Finally, here is an example of a table. But here too I am facing problem. The word Table is not in bold font. I would like to show it as \textbf{\textit{Table}}. What modification should be made in preamble ?

  • Perhaps to define a new command in the preamble? Put this in the preamble: \newcommand{\bi}[1]{\textbf{\textit{#1}}} where bi stands for bold and italic. Then, in the document, write \bi{Table} or \bi{Remark} or whatever word you wish to be marked up that way.

To change the format of the table caption you can use \captionsetup. For example, if you want to obtain the word and the number in bold-italic font you can use

\captionsetup{format=plain, labelfont={bf,it}}

For the bold-italic in remarks,... you can define a new theorem style:

\newtheoremstyle{bolditalic}
{3pt}
{3pt}
{\itshape}
{0pt}
{\bfseries\itshape}
{}
{.5em}
{}

Then place the \newtheorem behind calling the style, for example:

\theoremstyle{plain}
\newtheorem{thm}{Theorem}[section]
\newtheorem{cor}{Corollary}[section]
\newtheorem{lem}{Lemma}[section]

\theoremstyle{bolditalic}
\newtheorem{rem}{Remark}[section]

Edit: If in the table caption you only want to format the name but not the number, you can do something like this:

\DeclareCaptionLabelFormat{bfit}{{\bfseries\itshape#1} #2}
\captionsetup{labelformat=bfit,labelsep=quad}

Where #1 correspond to the word "Table" in this case. You ca see how to apply some basic formatting to that part in this example. The #2 correspond to the "number", if you want to format this part you can add something similar to the "#1" part.

  • Thanks a lot. It was really helpful. I faced another problem. Using the commands etc you suggested, when I compiled the tex file, I saw now Table is in bold and italics font, but as well as the Table number too is it bold and italics font. But I want only the caption word Table in bold and italics font, not the number. What shall I do ?
