\n\\begin{center}\n\\begin{tabular}{ |c|c|c| } \n \\hline\n cellnumber1 & cellnumber2 & cellnumber3 \\\\ \n cellnumber4 & cellnumber5 & cellnumber6 \\\\ \n cellnumber7 & cellnumber8 & cellnumber9 \\\\ \n \\hline\n\\end{tabular}\n\\end{center}\n\n<\/pre><\/div>\n\n\nThe above code creates three-column latex tables, each with three rows not separated by a line. We used the command { |c|c|c| }<\/em> to first declare three columns separated by vertical lines. The \u201cc<\/em>\u201d in the above command informs LaTeX to center the values in each column. Alternatively, we could use the parameter \u201cr<\/em>\u201d to align the column text towards the right, or \u201cl<\/em>\u201d to align it to the left.<\/p>\n\n\n\nWe used the command \\hline <\/em>twice to add horizontal borders to the top and bottom of the table. You can use this command as many times as needed to add horizontal borders to your tables.<\/p>\n\n\n\nWe then inserted our cell values \u201ccellnumber1<\/em>\u201d, \u201ccellnumber2<\/em>\u201d, and so forth. Each value in the code cellnumber1 & cellnumber2 & cellnumber3 \\\\<\/em> is separated by an \u201c&<\/em>\u201d. This \u201c&<\/em>\u201d informs LaTeX to separate the values individually in columns, while the \u201c\\\\\u201d indicates the end of a row.<\/p>\n\n\n\nIf we wanted to set up latex tables with horizontal lines between each row and no lines between columns, the code would resemble:<\/p>\n\n\n
\n\\begin{center}\n\\begin{tabular}{||c c c c||} \n \\hline\n Column1 & Column2 & Column3 & Column4 \\\\ [0.5ex] \n \\hline\\hline\n 1 & 232 & 486 & 524 \\\\ \n \\hline\n2 & 38 & 39 & 413 \\\\\n \\hline\n 3 & 747 & 831 & 5201 \\\\\n \\hline\n 4 & 604 & 13211 & 8184 \\\\\n \\hline\n 5 & 96 & 233 & 1681 \\\\ [1ex] \n \\hline\n\\end{tabular}\n\\end{center}\n\n<\/pre><\/div>\n\n\nIn the above code, we used the command \\hline\\hline<\/em>. This creates a gap between the first row containing our table headers and the second row that contains the first set of values. <\/p>\n\n\n\nWe also used the command \\begin{tabular}{||c c c c||} <\/em>to describe the table format. We wanted four values separated but without vertical column lines. The \u201c||\u201d<\/em> in this code inserts a double line at each side of the latex tables.<\/p>\n\n\n\n
