Consider the MWE below. If I \usepackage{floatrow} the longtable is not horizontal centered. If I comment out \usepackage{floatrow} the table is properly horizontal centered.

How can I get this snippet working (both use floatrow and center the longtable)?

Without usepackage floatrow in below MWE (correct):

With usepackage floatrow in below MWE (not centered anymore):

enter image description here


% >> 'PROBLEM' package
% << 'PROBLEM' package
Document is portrait
    \clearpage% Flush earlier floats (otherwise order might not be correct)
        \newgeometry{left=1cm, right=1cm,top=1cm,bottom=1cm}
    \begin{landscape}% Landscape page
        \centering % Center table
 \caption{Table is landscape.}
 \textbf{Col1} & \textbf{Col2}\tabularnewline
 \caption{Caption (Continued)}\tabularnewline
 \textbf{Col1} & \textbf{Col2}\tabularnewline
 A & B \tabularnewline
 C & D \tabularnewline
    \clearpage% Flush page
  • \centering never has any affect on longtable. – David Carlisle Jul 22 '16 at 19:17
  • Well, if you run MWE with usepackage{floatrow} commented out, you will see that it works. So if you say that it is not work, can you clarify why it nevertheless works? E.g. is it by default centering? – robert Jul 22 '16 at 19:18
  • longtables are centred by default unless you use [l] or [r] but \centering, \flushright don't do anything as they are always full width. – David Carlisle Jul 22 '16 at 19:20
  • So then the question is: why is this default behavior broken after importing floatrow, and how to fix it? – robert Jul 22 '16 at 19:22

For some strange reason floatrow sets \LTleft and \LTright to 0pt breaking longtable's default positioning, you could set them back, or simpler just use


to force longtable to centre.

this is sort of mentioned in the floatrow manual

Alignment Settings for longtable. The floatrow expands some settings of table lay- out to the longtable environment, so you may set \LTleft and \LTright parameters inside \DeclareMarginSet settings. For example, centering option was defined like: \DeclareMarginSet{centering}{\setfloatmargins{\hfill}{\hfill}% \LTleft=\fill \LTright=\fill}
