Graphics, Figures & Tables ⇒ Table output comes out very small

[dverdo96]

I am trying to include a table in my thesis and this is table number 5, all the other tables look nice when the file is compled but this one comes out with a very small text (see attachment), I don't understand why. This is the code of my table:

\begin{landscape}
\begin{table}[]
\caption{Experimental approaches chosen to address the aims with intended use and possible issues that they may present}
\label{techniques}
\resizebox{\textwidth}{!}{%
\begin{tabular}{llll}

Possible Issues \\
\rowcolor[HTML]{FFFFFF}
\multicolumn{4}{l}{\cellcolor[HTML]{FFFFFF}1. Collagen Characterisation} \\
\rowcolor[HTML]{FFFFFF}
\cellcolor[HTML]{FFFFFF} &
Mass Spectroscopy (MS) &
Analyse molecular mass of collagen dressings &
\begin{tabular}[c]{@{}l@{}}Mass range that can be analysed considering collagen chains exceeds the mass range limits of many spectrometers\\ Some dressings (e.g. Promogran\textsuperscript{\textregistered}) present cross-linked collagen so MS may not be fully applicable\end{tabular} \\
\rowcolor[HTML]{FFFFFF}
\cellcolor[HTML]{FFFFFF} &
Gel Electrophoresis (GE) &
Determination of protein purity and breakdown and possible identification of different collagen types through interrupted electrophoresis &
some dressings (e.g. Promogran\textsuperscript{\textregistered}) present cross-linked collagen so GE may not be fully applicable \\
\rowcolor[HTML]{FFFFFF}
\cellcolor[HTML]{FFFFFF} &
Circular Dichroism (CD) &
Study helicity of collagen fibres, and therefore denaturation of collagen in a biological process. Also used to study the enzymatic hydrolysis of collagen due to MMP-related reactions &
protein secondary structure analysis \\
\rowcolor[HTML]{FFFFFF}
\multirow{-4}{*}{\cellcolor[HTML]{FFFFFF}Structural Information} &
Differential Scanning Calorimetry (DSC) &
Bulk thermal properties of the material. Thermal properties of collagen-based scaffolds provide information on transitions in the structural state, reflecting initial primary (chemistry) sequence, structural state, and degree of crosslinking, and also purity of samples &
\begin{tabular}[c]{@{}l@{}}Small sample size required\\ Possibility of impurities\end{tabular} \\
\rowcolor[HTML]{FFFFFF}
\cellcolor[HTML]{FFFFFF} &
X-Ray Photoelectron Spectroscopy (XPS) &
Chemical composition of the sample. It allows to asses contaminants and material homogeneity &
Need to merge results of different technques for accurate nterpretation due to collagen analysis being very challenging \\
\rowcolor[HTML]{FFFFFF}
\cellcolor[HTML]{FFFFFF} &
Contact Angle Assay &
Assess hydrophilicity of dressings and therefore cellular attachment &
Need to merge results of different technques for accurate nterpretation due to collagen analysis being very challenging \\

Energy Dispersive X-Ray Spectroscopy (EDS or EDX) &
Surface elemental analysis &

Fourier-transform infrared spectroscopy (FTIR) &

Need to merge results of different technques for accurate nterpretation due to collagen analysis being very challenging \\
&
Atomic Force Microscopy (AFM) &
Anaysis of surface topography and roughness on the nanometre scale. Could be used to analyse morphological changes of the dressing during wound healing &
Soft samples may be difficult to analyse \\
&
SEM or ESEM &
Qualitative results about collagen structure retention in dressings and their structural changes when in presence of cells &
Only dry samples could be use. Cryo-SEM could be another option. \\
&
CT Scanning &
More comprhensive results in terms of 3D structure. Pore size and scaffold structure can be analysed. &
Training needed \\
\multirow{-4}{*}{Morphological Information} &
Live cell imaging &
Keratinocytes and fibroblasts migration across the dressing, to study bioresorbability &
Low contrast and need of very small sample \\
\multicolumn{3}{l}{2. Wound Model for in-vitro assay} &
\\
&
Fluorescent dyes &
Live/dead assay, col1, col3 etc. &

Confocal Quantitative Imaging Cytometer (CQ1) &
Live/dead assay, col1, col3 etc. &

\multirow{-3}{*}{Material-cell interaction} &
Apoptosis analysis &
Cytocompatibility &
Infection of cells during culture \\
Specific Inflammatory Response Mechanisms &
qPCR, flow cytometry, ELISA, immunohistochemistry &
M1 and M2 polarity, MMPs and TIMPs production, upregulated/downregulated inflammatory mediators (e.g. TNF-α, IL-1, IL-6, IL-8 . A look also at IL-4 and IL-10, responsible of keeping balance of pro-inflammatory mediators, could be useful). &
Training needed \\
\multicolumn{4}{l}{3. In-vivo assays} \\
Dressins effects in-vivo &
Rat/mouse model &
Wound model with dressing application &
Certification needed and difference of physiological behaviour of wound healing between rats/mice and humans

Thank you for your help

It is because of the \resizebox and very wide cells like

Code: Select all

\begin{tabular}[c]{@{}l@{}}Mass range that can be analysed considering collagen chains exceeds the mass range limits of many spectrometers\\ Some dressings (e.g. Promogran\textsuperscript{\textregistered}) present cross-linked collagen so MS may not be fully applicable\end{tabular}

I would suggest to remove the \resizebox an try a better designed tabular e.g. with p-columns or m-columns using array or even x-columns using tabularx instead of using tabulars with l-columns inside tabular cells.

BTW: If you'd expect suggestions with code, it would be useful, if you'd post a minimal working example instead of a code snippet. And please use code tags ("Code" button or "Select code" selector in the toolbar) to mark code in your posting.
