four in {$ xxx $}. Is there a way to specify the format of the
columns?
I am a little confused. Why do you need to do this? In your Latex, just enclose the whole output in an equation so the whole thing becomes in math mode.
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
\begin{array}{cccc}
1.2 & 1.0429 & \text{0.440773(65)} & 1.665\pm 0.0185 \\
1.3 & 2.9496 & \text{0.859618(21)} & 0.911\pm 0.0302 \\
1.4 & 0.9916 & \text{0.191505(74)} & 4.755\pm 0.0464 \\
1.5 & 1.6394 & \text{0.811863(52)} & 1.507\pm 0.0805 \\
\end{array}
\]
\end{document}
You can add the \[...\]
inside your latex document, or add it inside Mathematica, depending on how you are doing things. When you compile the above in Latex, here is the output

I'm using tabular
Well, you could always convert it by "hand" as this is easy enough. (this is how I actually generate all my Latex documents from Mathematica)
data = {{1.2, 1.0429, "0.440773(65)",
1.665 \[PlusMinus] 1.85*10^-2}, {1.3, 2.9496, "0.859618(21)",
0.911 \[PlusMinus] 3.02*10^-2}, {1.4, 0.9916, "0.191505(74)",
4.755 \[PlusMinus] 4.64*10^-2}, {1.5, 1.6394, "0.811863(52)",
1.507 \[PlusMinus] 8.05*10^-2}};
toX[s_] := ToString@TeXForm[s];
{nRow, nCol} = Dimensions[data];
s = "\\begin{tabular}" <> Table["c", {nCol}] <> "}
";
Do[
Do[
If[m == 1, s = s <> toX@data[[n, m]],
If[m == nCol, s = s <> "&{$" <> toX@data[[n, m]] <> "$}\\\\
", s = s = s <> "&" <> toX@data[[n, m]]]]
, {m, 1, nCol}
]
, {n, 1, nRow}
];
s = s <> "\\end{tabular}
";
s
Gives
\begin{tabular}{cccc}
1.2&1.0429&\text{0.440773(65)}&{$1.665\pm 0.0185$}\\
1.3&2.9496&\text{0.859618(21)}&{$0.911\pm 0.0302$}\\
1.4&0.9916&\text{0.191505(74)}&{$4.755\pm 0.0464$}\\
1.5&1.6394&\text{0.811863(52)}&{$1.507\pm 0.0805$}\\
\end{tabular}
Compiles as

Do you want frame? Then do
data = {{1.2, 1.0429, "0.440773(65)",
1.665 \[PlusMinus] 1.85*10^-2}, {1.3, 2.9496, "0.859618(21)",
0.911 \[PlusMinus] 3.02*10^-2}, {1.4, 0.9916, "0.191505(74)",
4.755 \[PlusMinus] 4.64*10^-2}, {1.5, 1.6394, "0.811863(52)",
1.507 \[PlusMinus] 8.05*10^-2}};
toX[s_] := ToString@TeXForm[s];
{nRow, nCol} = Dimensions[data];
s = "\\begin{tabular}{" <> Table["|c", {nCol}] <> "|}\\hline
";
Do[
Do[
If[m == 1, s = s <> toX@data[[n, m]],
If[m == nCol, s = s <> "&{$" <> toX@data[[n, m]] <> "$}\\\\\\hline
", s = s = s <> "&" <> toX@data[[n, m]]]]
, {m, 1, nCol}
]
, {n, 1, nRow}
];
s = s <> "\\end{tabular}
";
s
gives
\begin{tabular}{|c|c|c|c|}\hline
1.2&1.0429&\text{0.440773(65)}&{$1.665\pm 0.0185$}\\\hline
1.3&2.9496&\text{0.859618(21)}&{$0.911\pm 0.0302$}\\\hline
1.4&0.9916&\text{0.191505(74)}&{$4.755\pm 0.0464$}\\\hline
1.5&1.6394&\text{0.811863(52)}&{$1.507\pm 0.0805$}\\\hline
\end{tabular}
Which compiles as
